Triangle A C B is shown. Angle A C B is a right angle. The measure of angle A is 15°, and the length of side BC is 8. What are the lengths of the other two sides, rounded to the nearest tenth? AC = AB =

Respuesta :

Answer:

AB= 32

AC=31

Step-by-step explanation:

BC is the opposite of angle A, which measure 15 degrees.

There is a formula, leg opposite to 30 degree angle is half the hypotenuse.

In the same way, there is another formula, leg opposite to 15 degree angle is 1/4 the hypotenuse.

8 is 0.25 the hypotenuse.

AB or BA is 32.

According to pythagorean theorem, [tex]\sqrt{32^2-8^2} = AC[/tex]

[tex]AC= \sqrt{960}[/tex]

To the nearest tenth, AC=31

Hope this helps ;)
