Question

the fig consist of an equilateral triangle and an issoceles triangle.Find angle x​

Answer 1

An equilateral triangle has 3 equal sides and angles

they are 60°

the angle in the bottom right of the equilateral triangle is 60°

then the bottom left of the iscoceles triangle is 180-60=120° (linear pair)

the isocsles triangle has two equal angles and sides

so 120+2x=360

2x=360-120

2x=240

x=240÷2

120
