Question

in triangle ABC , if angle A : angle B:angle C=2:4:4 then find the measure of angle A ,angle B and angle C ​

Answer 1

The sum of angles :— 2x + 4x + 4x = 180°

10x = 180°

x = 18°

Now, putting x= 18° for A=2x , B=4x and C=4x.

A= 2 X 18° = 36° and B = C = 4 X 18° = 72°.

And if you will add A, B and C you will get 180° which shows that it is a triangle.

Hope this helps!

Answer 2

Answer:

total measure of interior angles of a triangle=180

2x+4x+4x=180

10x=180

x=180/10

x=18

Angle A= 36 B=72 C=72 (Multiply 18 with the ratios)
