In ΔFGH, the measure of ∠H=90°, GF = 41, HG = 40, and FH = 9. What ratio represents the cosine of ∠F?

Cosine F = (40 / 41)

Step-by-step explanation:

Since it's a right angle triangle, we can use

SOHCAHTOA method.

Where CAH = cosine F = adjacent / hypotenus.

Opposite (FH) = 9

Adjacent (HG) = 40

Hypothenus(FG) = 41

Cosine F = adjacent / hypothenus

Cosine F = 40 / 41

Cosine F = 0.9756

F = cos⁻(0.9756)

F = 12.68°

See attached document for better illustration on the triangle.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day
