find the cosine of ∠g.

write your answer as an integer or as a decimal rounded to the nearest hundredth.

cos(g) =

Step-by-step explanation:

Triangle IGH is a right angle triangle.

From the given right angle triangle

GH represents the hypotenuse of the right angle triangle.

With ∠G as the reference angle,

GI represents the adjacent side of the right angle triangle.

HI represents the opposite side of the right angle triangle.

To determine GH, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

GH² = 45² + 28²

GH² = 2025 + 784 = 2809

GH = √2809 = 53

To determine Cos G, we would apply trigonometric ratio

Cos θ = opposite side/hypotenuse. Therefore,

Cos G = 28/53

Cos G = 0.53

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

they would have to work 32 hours.
