Answer:
Part 1)
Part 2)
Part 3) and
Step-by-step explanation:
see the attached figure with letters to better understand the problem
step 1
Find the side b
we know that
In the right triangle ABC
The function sine of angle B is equal to divide the opposite side angle B (AC) by the hypotenuse (AB)
we have
substitute
solve for b
step 2
Find the side a
we know that
In the right triangle ABC
The function cosine of angle B is equal to divide the adjacent side angle B (BC) by the hypotenuse (AB)
we have
substitute
solve for a
step 3
Find the measure of angle A
we know that
In the right triangle ABC
----> is a right angle
∠A+∠B=90° ------> by complementary angles
substitute the given value
This is the Equation: 2x + 6
