Question

Find the value of the unknown interior angle x in each of the following diagrams:

Answer 1

Hlo mate here is your answer!!☺ a)solve:-let the angle of triangle be ABC

let A be=50°

let B be=115°

let C be =x

The sum of triangle=360°

A+B+C=180°

50°+155°+x=360°

205+x=360°

x=360-205

x=155°

b)A+B+C=360°

80°+30°+x=360°

110°+x=360°

x=360°-110°

x=250°

c)A+B+C=360°

70°+36°+x°=360°

106+x=360°

x=360°-106°

x=254
