The sum of the measures of two exterior angles of a triangle is 252. What is the measure of the third exterior.
Answer:
108°
Step-by-step explanation:
The sum of the exterior angles = 360°, thus
third = 360° - 252° = 108°
Answer:

Which of the following side lengths can form a triangle?
21 cm, 23 cm, and 44 cm
14 ft, 17 ft, and 30 ft
2 in, 3 in, and 7 in
12 mm, 36 mm, and 53 mm
Answer: 14, 17, 30
Step-by-step explanation:
In order to form a triangle, the sum of two sides must be GREATER than the third side for all combinations:
a + b > c & a + c > b & b + c > a
21 + 23 = 44 which is NOT greater than 44
2 + 3 = 5 which is NOT greater than 7
12 + 36 = 48 which is NOT greater than 53
14 + 17 > 30 & 14 + 30 > 17 & 17 + 30 > 14
so these side length form a triangle
What is the surface area of the triangular prism?
A triangular prism. The rectangular sides are 20 feet by 3 feet, 20 feet by 4 feet, and 20 feet by 5 feet. The triangular sides have a base of 3 feet and height of 4 feet. [Not drawn to scale]
152 square feet
172 square feet
252 square feet
264 square feet
Answer:
252
Step-by-step explanation:
I think I may be wrong
The surface area of the triangular prism is: 252 square feet
What is a triangular prism?A triangular prism is a solid three-dimensional shape with three rectangles and two triangles.
Analysis:
Surface area of triangular prism = area of 3 rectangles + area of two triangles
Surface area = 20 x 4 + 20 x 5 + 20 x 3 + 2 x ( 1/2 x 3 x 4) = 252 square feet
In conclusion, the surface area of the triangular prism is 252 square feet.

Can someone help me pls
Answer:
b= 4
Step-by-step explanation:
b-1.6= 2.4
I would add 1.6 to both sides so that b could be on one side. The opposite of -1.6 is 1.6, so b-1.6+ 1.6= 2.4
b= 2.4+ 1.6
Since -1.6+1.6 cancel out, I get b= 2.4+1.6. I add 2.4+ 1.6 to get 4.
b=4
So, b= 4
To check my work I would plug in b back into the equation:
So...
b=4
b-1.6= 2.4
4-1.6= 2.4
Answer:
B=4

What is the length of the unknown side of the right triangle?
A right triangle with hypotenuse x and legs 5 and 12
13
17
25
60
Answer:
13
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem
[tex]a^2+b^2=c^2[/tex]
where a and b are the legs and c is the hypotenuse.
We know that the legs are 5 and 12. We also know the hypotenuse is x, or unknown.
Substitute 5 in for a, 12 for b, and x for c.
[tex]5^2+12^2=x^2[/tex]
Evaluate the exponents.
5^2 is the same as 5*5, which is 25.
12^2 is the same as 12*12, which is 144.
[tex]25+144=x^2[/tex]
Add 25 and 144
[tex]169=x^2[/tex]
We are trying to find out what x is. In order to do this, we have to get x alone. Since x is being squared, take the square root of both sides. The exponent and square root will cancel, leaving x by itself.
[tex]\sqrt{169} =\sqrt{x^2} \\\\\sqrt{169}=x\\13=x[/tex]
The hypotenuse is 13.
So the right answer is 13.

1.) The population of a certain city decreased by 10,000 people.
Write a signed number to represent this population change.
2.) A car corporation produced 520 fewer cars this month than last.
Write a signed number to represent this month's change in production
Step-by-step explanation:
1. A decrease means that the 10,000 will be negative, and therefore the answer is -10,000.
2. Fewer means a decrease, and a decrease means that the 520 will be negative. The answer is -520.

Answer:
y = 3/4x
Step-by-step explanation:
We need to find the slope of the line
We have point (0,0) and point (4,3)
m = (y2-y1)/(x2-x1)
= (3-0)/(4-0)
=3/4
The y intercept is 0 since it crosses the y axis at 0
The slope intercept form of the line is
y = mx+b
y = 3/4x +0
y = 3/4x
Find the value of x in the diagram below. Show your work.

Answer:
13 degrees
Step-by-step explanation:
85 and A are opposite hence equal so A = 85
98 and C are equal because they are corresponding angles hence C = 98
B and C are in a straight line so they add up to 180
B = 180-98 = 82
Finally, A and B and X add to 180 because they for a triangle
X+85+82 = 180
X= 13 degrees
Angles y and z are complimentary. If angle y is 18°, what is the measure of angle z?
18°
36°
72°
162°
Answer:
z = 72°
Step-by-step explanation:
Complimentary angles sum to 90° , thus
z + y = 180, that is
z + 18 = 90 ( subtract 18 from both sides )
z = 72°
So the right answer is 72 degree.

Which form most quickly reveals the vertex?
Choose 1 answer:
m(x) = -2(x - 6)^2 + 18
m(x) = -2(x - 3)(x -9)
m(x) = -2x^2 +24x- 54
Answer:
first option
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
m(x) = - 2 (x - 6)² + 18 ← is in vertex form
with vertex = (6, 18 )

Answer:
a= 13+3b
Step-by-step explanation:
Simplifying
a + -7 = 3(b + 2)
Reorder the terms:
-7 + a = 3(b + 2)
Reorder the terms:
-7 + a = 3(2 + b)
-7 + a = (2 * 3 + b * 3)
-7 + a = (6 + 3b)
Solving
-7 + a = 6 + 3b
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + a = 6 + 7 + 3b
Combine like terms: -7 + 7 = 0
0 + a = 6 + 7 + 3b
a = 6 + 7 + 3b
Combine like terms: 6 + 7 = 13
a = 13 + 3b
Simplifying
a = 13 + 3b

5. Cameron found the volume of the cone below, but when he double-
checked his work, he got a different solution. Determine which solution
best represents the volume of the cone.
TRY #1
169.6 in 3
TRY #2
56.5 in 3
Answer:
Try 2 is correct
Step-by-step explanation:
See attachment for dimension of cone.
From the attached,
The diameter of the cone, d = 6 in
The height of the cone, h = 6 in
The volume of a cone is calculated as thus
Volume = ⅓πr²h
So, we need the value of r.
r represents radius and
r = ½d
r = ½ * 6
r = 3.
So,
Volume = ⅓πr²h becomes
Volume = ⅓ * π * 3² * 6
Volume = π * 3 * 6
Volume = π * 18
Volume = 18π
Take π as 3.14
So,
Volume = 18 * 3.14
Volume = 56.52 in³
Given that
Try 1 = 169.6 in³
Try 2 = 56.5 in³
We can conclude that Try 1 is incorrect and Try 2 is correct

A) 1/2
B) 2/3
C) 2/9
D) 3/4
Answer:. 1/2
Step-by-step explanation: Different ways to get this.
PEMDAS: figure 8 squared is 64 and 2 cubed is 8. Multiply to get 512 in the numerator.
Figure 4 cubed is 64 and (-2)^4=16. Multiply to get 1024 in the denominator. Simplify to 1/2
You could express all the factors as 2 to some power then add and subtract the exponents.
2^6 •2^3=2^9. Over
2^6 • 2^4 = 2^10. Subtract exponents. 2 to the -1 power is 1/2.
