which is the best estimate for the perimeter of the triangle? round to the nearest tenth
20.0 in
23.1 in.
23.7 in.
27.4 in

23.7 inches.

Step-by-step explanation:

See the attached diagram.

A triangle ABC has angles that measure 30°, 60°, and 90°.

Now, the hypotenuse BC = 10 inches.

Then using trigonometry  

⇒ inches.

Again,

⇒ inches.

Therefore, the perimeter of the triangle ABC will be equal to (AB + BC + CA) = (5 + 10 + 8.66) = 23.66 inches ≈ 23.7 inches. (Answer)

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
