Question

Lesson 13.2 Checkpoint
Find the unknown length x in each right triangle, to the nearest tenth.

Answer 1

x≈46.7 m<u≈ 47 m<w≈43

Explanation:

sin24=19/x

19/sin24≈46.7=x

m<u=sinu=11/15

arcsin11/15≈47

m<w=cosw=11/15

arccos11/15≈43

Answer 2

Explanation:

1.

x/ sin 90 = 19 / sin 24 --> x ≈ 46,71
