Two sides of a triangle are equal in length. The length of the third side exceeds the length of one of the other sides by 3 centimetres. The perimeter of the triangle is 93 centimetres. Find the length of each side of the triangle
Answers
Answer:
it must be 30, 30, 33
Step-by-step explanation:
first, divide 93 by 3, since a triangle has 3 sides, you would get 31, yet if you took away that three in 93, it'd be 30. For that one that exceeds the others by 3, add the three to one of the thirds, and the other two are just the same, so when it said, "exceeds the length of one of the other sides," It didn't really change anything, because the other side is just as long.

Can you guys help me with this angle problem for Geometry tysm
Answers
Answer:
You need to solve for x
Step-by-step explanation:
3x + 5 + 10x - 7 = 180
13x + 5 - 7 = 180
13x - 7 = 175
13x = 182
x = 14
Plug in x
3(14) + 5 for QRT and 10(14) - 7 for TRS
QRT = 47 and TRS = 133
Answer:
QRT = 47
TRS = 133
Step-by-step explanation:
The two angles form a straight line so they add to 180
3x+5 + 10x-7 = 180
13x-2 =180
Add 2 to each side
13x-2+2 =180+2
13x= 182
Divide by 13
13x/13 = 182/13
x =14
We want QRT = 3x+5 = 3*14+5 = 42+5 = 47
TRS = 10x-7 = 10*14-7 = 140-7 = 133

What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
We have to find the measure of angle RIA
The opposite angle of RIA is LIK
Let us find the measure of LIK
∠FIL+∠LIK+∠KIN=180
30+∠LIK+95=180
∠LIK + 125 =180
Subtract 125 from both sides
∠LIK = 180 - 125
=55 degrees
∠LIK is equal to ∠RIA
∠RIA = 55 degrees
Hence, the measure of angle RIA is 55 degrees, option A is correct.

The variables x and y are related proportionally. When x = 8, y = 20. Find y when x = 80.
Answers
Answer:
y = 200
Step-by-step explanation:
Use the equation y = kx, where k is a constant.
Plug in the given x and y values, then solve for k:
y = kx
20 = k(8)
2.5 = k
Then, plug in k and the given x value, and find y:
y = 2.5x
y = 2.5(80)
y = 200
So, y = 200 when x = 80

B. y=-3/2x +24
C. y= 2/3x + 14
D. y= 2/3x + 8
Answers
Answer:
B. y = -3/2x + 24
Step-by-step explanation:
The perpendicular slope is -3/2x to find the y-intercept use the point given
Plug in
6 = -3/2(12) + b (b = y-intercept)
6 = -18 + b (add 18 on both sides)
24 = b (so)
y = -3/2x + 24

Answers
Answer:
44 degrees
Step-by-step explanation:
Because a right angle triangle if added all angles will=to 180 degrees
so 46+90=136
180-136=44
Answer:
44
Step-by-step explanation:
You add 46 to the 90 degree angle (right angle) and get 136. Then, because the angles of a triangle add up to 180 degrees all the time, you would do 180-136 and get 44.

Step-by-step explanation:
a. Determine the following descriptive characteristics for the weights of the females: mean, variance, and standard deviation. Is this a sample or population? Again, pay attention to number of decimal places and appropriate units.
a) Female: 2.45 2.57 2.81 2.37 2.01 2.50 2.32
Mean
The formula = Sum of term/ Number of terms
Mean = 2.45 + 2.57 + 2.81 + 2.37 + 2.01 + 2.50 + 2.32/7
17.03/7
= 2.432857143kg
Variance
This is a population
Hence: The formula for Population variance =
= (X - Mean)²/N
Where N = Number of terms = 7
= (2.45 - 2.432857143)² + (2.57 -2.432857143)² + (2.81 -2.432857143)² + (2.37- 2.432857143)²+ (2.01 - 2.432857143)²+ (2.50 - 2.432857143)² + (2.32 - 2.432857143)² /7

= 0.3613428572/7
= 0.05162040817kg
Standard Deviation

b. Determine the mean, variance, and standard deviation for the male weights
Male 2.86 2.65 2.75 2.60 2.30 2.49 2.84
Mean
The formula = Sum of term/ Number of terms
= 2.86 + 2.65 + 2.75 + 2.60 + 2.30 + 2.49 + 2.84/7
= 18.49/7
= 2.641428571 kg
Variance
= ( 2.86 -2.641428571)² + (2.65 - 2.641428571)² + (2.75 -2.641428571)² + (2.60 +2.641428571)² + (2.30 - 2.641428571)² + (2.49+2.641428571)² (2.84 + 2.641428571)²/7
