The expressions given represent the measures of the acute angles of a right triangle Find the measure of each acute angle.

Answers

Answer 1

Answer:

30, 60

Step-by-step explanation:

The sum of a triangles angles should be 180.

Subtract 90 because it's a right triangle.

180 - 90 = 90

Now we know the sum of the other angles should be 90.

x + 2x = 90

Solve for x.

3x = 90

x = 30

Now you substitute 30 for x.

(30), 2(30)

30, 60

Construct a linear function that has a slope of -3 and passes through the point (−2,3)

Answers

Answer:

f(x) = -3x - 3

Step-by-step explanation:

you can use the point-slope form to help you.

[tex]y - y_{1} = m (x - x_{1} )[/tex] m = slope and [tex](x_{1} , y_{1}) = (-2, 3)[/tex]

So, y - 3 = -3(x + 2)

y - 3 = -3x - 6

y = -3x - 3 or f(x) = -3x - 3

[tex]f(x) = -3x - 3[/tex]You can use the standard form y = mx + c to build that linear relationship.

Thus, the needed linear function is: [tex]f(x) = -3x -3[/tex]

Given that:The line has slope of -3The line passes through (-2,3)To find:

The linear function

Relation between linear function and straight line:

A linear function of two variables is always an equation of a straight line and can be converted into standard form y = mx + c (assuming m and c to be finite constants and x and y are variables).

m denotes slope of this line and c denotes intercept on y axis by this line.

If linear function is not of two variables, then we can take the output f(x) as value of second variable.

Since the slope is already given, thus, we have the equation as:

y = -3x + c

Now, since the line passes through (-2,3), thus it must satisfy the equation since the point is member of the family of points who constitute this line(and since the equation shows family of such points, thus the point should satisfy the equation).

Thus,

[tex]y = -3x +c|{(x,y) = (-2,3)}\\ 3 = -3 \times -2 + c\\ 3 = 6 + c\\ c = 3 - 6\\ c = -3[/tex]

Thus, we have the equation of the straight line in consideration as:

y = -3x -3

y is function of x, thus can be rewritten as [tex]f(x) = -3x -3[/tex] (assuming f doesn't represent any other function as we can't use used symbols in a context to prevent ambiguity)

Thus, the needed linear function is: [tex]f(x) = -3x -3[/tex]

Answers

Answer:

104°+33°+(5x+13)°=180°[all angle sum is 180°]

137°+(5x+13)=180°

137°+13+5x=180°

150°+5x=180°

5x=180°-150°

5x=30

x=30/5

×=6

Answer:

x = 6

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

5x + 13 + 104 + 33 = 180, that is

5x + 150 = 180 ( subtract 150 from both sides )

5x = 30 ( divide both sides by 5 )

x = 6

An airplane climbs at an angle of 16° with the ground. Find the ground

Please help me with this!

Answers

Answer:

2403.2

Step-by-step explanation:

We get the length of the hypotenuse, and the base angle. To find the length of the base, we use the cosine of 16° since it is equal to the adjacent side length/ hypotenuse side length or cos 16°= x/2500. The isolate x by multiplying both sides by 2500. The cos 16° is around 0.96126, multiplied by 2500 (cos 16°(2500)) = 2403.1

c. Which blood type has less than 10 donors?
blood type percent
O 45
A 40
B 11
AB. 4

Answers

Answer:

Answer:

a. 16

b. 80

c. Blood type AB

Step-by-step explanation:

Given:

O = 45%

A = 40%

B = 11%

AB = 4%

Total number of donors = 145

a. No. of donors that had type B blood =

Type B blood donors ≈ 16

b. No. of blood donors without blood type O =

Those without blood type O ≈ 80

c. Find the number of people that had type AB:

Type AB = ≈ 6. This is less than 10 donors.

Therefore, blood type AB had less than 10 donors.

Answers

Answer: No, the correct answer is 320.

Step-by-step explanation: To solve for Y, simplify both sides of the equation, then isolate the variable.

Step 1: Multiply both sides by 8.

[tex](\frac{y}{8} )\times(8)=(40)\times(8)=320[/tex]

Therefore, your answer is incorrect, the correct answer is 320.
