Question

Solve for z. Round to the nearest tenth, if necessary.
28
▷
B
X

Answer 1

x ≈ 2.1

Explanation:

using the tangent ratio in the right triangle

tan28° =
`(opposite)/(adjacent)` =
`(BC)/(AB)` =
`(x)/(4)` ( multiply both sides by 4 )

4 × tan28° = x , then

x ≈ 2.1 ( to the nearest tenth )
