Question

18
61°
Find missing side round to nearest tenth

Answer 1

x = 9.9 or 10

Explanation:

to find missing angle -->

90 + 61 + z = 180

151 + z = 180 *subtract 151 from both sides*

z = 29

to find x -->

tan (29) = x/18 *put tan(29) over 1 then cross multiply*

x = 18 (tan(29))

x = 9.97 --> round up to 10
