2 trig ratios missing sides and angels

1 answer:

8 0

Answer:

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos66° = $\frac{adjacent}{hypotenuse}$ = $\frac{13}{x}$ ( multiply both sides by x )

x × cos66° = 13 ( divide both sides by cos66° )

x = $\frac{13}{cos66}$ ≈ 32.0 ( to the nearest tenth )

putting value of 2y in equation (2)

4x+15-3x=20

x=5

then after , putting value of x in eq(3)

y=(15-15)/2

y=0
