The measures of two angles of a triangle are 75 and 62º. Find the measure of the third angle.
13°
c. 470
b. 43°
d. 137

Answers

Answer: B 43

Step-by-step explanation:

Well for a triangle it has to be equal to 180 so you would add 75 and 62 to get 137 so you would add each answer to 137 and whichever one equals 180 is the answer therefor stating that the answer is B 43.

By hand or by using a drawing program, sketch a design of Ray and Kelsey's coaster that includes the shape of the g(x) and f(x) functions that you chose in the Parts A and B. You do not have to include the coordinate plane.

26-12=14

14/7=2

?-9=2

?=11

Answer:

g = 11

Step-by-step explanation:

⇒ 26 -12 = 7(g - 9) + 12 -12

⇒ 14 = 7(g - 9)

⇒ 14/7 = 7(g - 9)/7

⇒ 2 = g - 9

⇒ 2 +9 = g - 9+9

⇒ 11 = g

Answers

Answer:

I believe your answer would be

Step-by-step explanation:

Using that formula, we can substitute in the values we need that are given to us in the question:

h = 12

r = 4

Now we need to use the formula.

V = 1/3 (pi) (4²) (12)

First lets do the exponent.

4² = 16

V = 1/3 (pi) (16) (12)

Now lets do pi × 16.

pi × 16 = 50.2654824574.

Now we have:

V = 1/3 (50.2654824574) (12)

Multiply 50.2654824574 and 12.

50.2654824574 × 12 = 603.185789489

Now all we have:

V = 1/3 (603.185789489)

Multiply them.

V = 201.06192983

So, your answer is V ≈ 201.06192983, or 201.
