Question

Find the value of x. Round to the
nearest tenth.
12
X=[?]

Answer 1

9.8

Explanation:

two angles are given, 35 and 90. subtract these from 180 to get 55, the corresponding angle of x. we can then use law of sin to solve.

sin90/12 = sin55/x

sin55 * 12 = 9.8 , 9.8 = sin90x , 9.8/sin90

=9.8
