Question

Write your answer as an integer or as a decimal rounded to the nearest tenth.

Answer 1

GI = 6.7

Explanation:

Trigonometry Ratios:

Hypotenuse is given and we need to find GI - Adjacent side of ∠42°.

`\sf Cos \ \angle 42^\circ = (adjacent \ side)/(hypotenuse)\\\\Cos \ \angle42^\circ = (GI)/(9)\\\\0.7431 = (GI)/(9)`

0.7431* 9 = GI

GI = 6.6879

GI = 6.7
