Question

Equilateral triangle ABC is drawn inside AB of square, ABDE. Find the measure of "X" shown in the figure.

Answer 1

Answer:

240 degrees

Step-by-step explanation:

In an equilateral triangle each angle measures 60 degree. And the measure of one point is 360 degree so we will subtract 60 from 360. After that there is an another equilateral triangle ABE so we will again subtract 60 degrees.

I hope it was understandable. Please mark as brainliest

Answer 2

Answer:

225 degrees

Step-by-step explanation:

Angle of Equilateral Triangle = 60°°

Diagonal is the angle bisector for vertex angle of the square. Thus it will be divided into 2 parts of 45°° each.

Thus the value of x = 360°°-(Sum of Equilateral Triangle angle and 45°°)

i.e x=360-(60+45)=360-105=255°
