In triangle ABC, if angle A: B: C = 2:5:2. then find all the angles of triangle ABC​

Answer 1

Answer:

40 degrees

Step-by-step explanation:

Let the angle A be 2x, angle B be 5x, and angle C be 2x

then,

we know that the sum of all angles of a triangle is 180degree

2x+5x+2x= 180 degree

9x= 180 degree

x= 20 degree

Now,

angle A= 2x

= 2*20 degree

= 40 degree

angle B = 5x

= 5* 20 degree

= 100 degree

angle C = 2x

= 2*20 degree

= 40 degree
