Question

Find the third angle

Answer 1

Answer:

There are 4 triangles in the given figure.

Step-by-step explanation:

The sum of all the angles in the triangle is 180 degree.

1. Angle A is 50,Angle be should be 50 degree angle c is 80 degree.

2.Here x should be 60 degree because the other angle are 60 degrees

3.2x+3x+x=180°

5x+x=180 degree

6x=180 degree

x=180/6

x=30 degree

if x is 30 degree then 2x is 60 degree, then 3x is 90 degree.

4.here x is 40 degree because m angle is 100 and L angle is 40
