Answer:
Step-by-step explanation:
<h3>Given</h3>
- sin θ = 3/5
- cos α = 3/5
- Both angles are acute
<h3>Solution</h3>
Since both sin θ and cos α have same value of 3/5 and both angles are in the I quadrant, the angles θ and α are complementary.
<u>It means: </u>
- θ + α = 90°
- sin (θ + α) = sin 90° = 1
Answer:
alpha=cos^-1(0.6)
alpha=53°
sin(37+53)
=1
