Question

Find the value of x.

Answer 1

The measure of the missing angle x is 23.22 degrees

Cosine rule

The expression for representing cosine rule is expressed as:

c² = a² + b² - 2ab cos C

Given the following parameters

a = 26

b = 50

c = 29

Substitute

c² = a² + b² - 2ab cos C

29² = 26² + 50² - 2(26)(50) cos C

841 = 676 + 2500 - 2600cosC

2335 =2600cos C
cos C = 2335/2660

C = 23.22 degrees

Hence the measure of the missing angle x is 23.22 degrees
