Question

The sum of measures of angles is 180 degrees . Find the value of x in the given figures.
it's urgent pls answer it in a notebook pls ​

Answer 1

Answer:

a) 70° + 45° + x = 180°

=> x = 180° - (70° + 45°)

=> 180° - 115°

=> 65°

Ans. 65°

b) x + x + 110° = 180°

=> 2x = 180° - 110°

=> 2x = 70°

=> x = 70°/2

=> x = 35°

Ans. 35°

Hope it helps.

Answer 2

a)45°+70°+x=180°(angle sum property of a triangle)

115°+x=180°

x=180-115=65°

x=65°

b)110°+x+x=180°(angle sum property of a triangle)

110°+2x=180°

2x=180-110=70

x=70/2=35°

x=35°
