Question

The triangle shown has a hypotenuse with a length of 13 feet. The measure of angle A is 20 degrees. and the measure of angle B is 70 degrees. Which of the following is closest to the length, in feet, of line segment AC? No need to use a calculator to find the trig numbers. Each function is listed below.

4.4
5
12.2
35.7

Answer 1

Answer:

$AC=12.2\ units$

Step-by-step explanation:

we know that

In the right triangle ABC

$sin(70\°)=\frac{AC}{AB}$

Solve for AC

$AC=ABsin(70\°)$

substitute the values

$AC=13(0.9397)=12.2\ units$
