Question

Find the value of x

Answer 1

STEPS

x + 110 + 120 = 360

x + 230 = 360

x = 360 - 230

x = 130

ANSWER

x = 130°

Answer 2

It's a triangle

Firstly we will find the interior angles

So,

Angle A = 180-110= 70° {Linear pair}

Angle C= 180-120 = 60° {Linear pair}

Angle B = 360- (70+60) { Angle sum property}

= 180- 130= 50°

x= 180-50 { Linear pair}

= 130°
