7- relationship between height and hair color

Step-by-step explanation:

We need to use law of sin

sin A/a = sin B/b

a is a side opposite to the angle A,

b is a side opposite to the angle B.

We can write

sin 75⁰/22 = sin x/12

sin x = (12*sin 75⁰)/22

x= sin⁻¹((12*sin 75⁰)/22≈ 31.8⁰

x ≈ 31.8⁰
