Question

Find x

a) 75°
b) 70°
c) 80°
d) None of these​

Answer 1

a)75°

Step-by-step explanation:

linear pair,

125°+ z = 180°

z = 180°-125°

z = 55°

linear pair,

130°+y = 180°

y = 180°-130°

y = 50°

Angle sum property of triangle,

x+y+z = 180°

x + 50° + 55° = 180°

x = 180°-105°

x = 75°

Answer 2

Answer:

a) 75°

Step-by-step explanation:

area of triangle is 180

the angle of straight line is 180

180-125=55

180-130=50

50+55+x=180

105-x=180x=180-105

x=75
