Answer:
θ ≈ 17.1°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan θ = = = , then
θ = ( ) ≈ 17.1° ( to the nearest tenth )
5 1/2 - 4 1/6
= (5 - 4) + (1/2 - 1/6)
= 1 + (3/6 - 1/6)
= 1 + 1/3
= 1 1/3
8 1/4 - 3 1/8
= (8 - 3) + (1/4 - 1/8)
= (8 - 3) + (2/8 - 1/8)
= 5 + 1/8
= 5 1/8
3 1/2 - 2 1/8
= (3 - 2) + (1/2 - 1/8)
= (3 - 2) + (4/8 - 1/8)
= 1 + 3/8
= 1 3/8
