Answer:

Part 1)
AB=30.9\ units

Part 2)
AC=29.9\ units

Explanation:

The picture of the question in the attached figure

Part 1

Find the length side AB

we know that


sin(A)=(BC)/(AB) ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values


sin(15^o)=(8)/(AB)

solve for AB


AB=(8)/(sin(15^o))=30.9\ units

Part 2

Find the length side AC

we know that


tan(A)=(BC)/(AC) ----> by TOA (opposite side divided by the adjacent side)

substitute the given values


tan(15^o)=(8)/(AC)

solve for AC


AC=(8)/(tan(15^o))=29.9\ units

The measure of angle A is 15°, and the length of side BC is 8. What are the lengths-example-1
