Please someone help me

Answer 1

use sohcahtoa; tan is the easiest to use for this one

Answer 2

∠ XYZ ≈ 72.9°

Explanation:

Using the tangent ration in the right triangle

tan XYZ =
`(opposite)/(adjacent)` =
`(XZ)/(XY)` =
`(13)/(4)`, thus

XYZ =
`tan^(-1)`(
`(13)/(4)`) ≈ 72.9° ( to 1 dec. place )
