Hello i really need help, please help me. thank you :(

Answer 1

cosФ=12/13

Ф=34.57 degrees

Explanation:

cosФ=adj/hyp

cosФ=24/26=12/13=0.923076

Ф=34.57 degrees

Answer 2

12/13

Explanation:

The cosine of an angle in a triangle can be calculated as a relation between the adjacent side and the hypothenuse. So, in this case the adjacent side of θ is 24 and the hypothenuse is 26.

Then:

cos(θ) = 24/26 = 12/13
