R = A / tetha
70° × pi/180 = radian
radian = 1.222 rad
3 = A / 1.222

<h3>Cosine rule</h3>
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
