Answer: 12.22

Explanation:

Since it is a right angled triangle, we use the trigonometry method of solving triangles for this question.

The given angle is 42° and we recall our trigonometry functions of

Sin Φ = opposite/hypotenuse

Cos Φ= adjacent/hypotenuse

tan Φ = opposite/adjacent

Where

Φ =42°

Opposite of the angle = GH = 11

Adjacent of the angle = HI = ?.

Hence we use the tan Formula.

tan 42 = 11/HI

HI = 11/tan42

HI = 11/0.90

HI = 12.22
