Question

Yo, I need some help on this. I've been stuck on this for hours now. I took all the notes in class and paid attention but can't just seem to figure this out. I have answers on some of the questions but I'm still confused. Please help me learn how to do this easier ;-;​

Answer 1

1. ∠B
2. 1/2
3. ∠C
4. 5/7

Explanation:

Reference angle :

• The angle which is indicated by a small arc inside the triangle

Sine ratio :

• The ratio between the side opposing the angle and the hypotenuse

Solving :

1. Reference Angle = ∠B
2. Sine ratio = 7/14 = 1/2
3. Reference angle = ∠C
4. Sine ratio = 25/35 = 5/7
