Question

Each of the two angles of an isosceles triangle is twice the third angle.Find the angles of the triangle .

Answer 1

Answer:

let angle a,b,c = X

x+x+x=180

3x=180

x=180/3

x=60

check

a+b=120

c=60

120/60=2

Step-by-step explanation:

letter taking angle A Angle B and angle C is equals to X so and Angle A + Angle B + angle C is equals to 180 due to angle sum property X + X + X is equals to 3 x if 180 is divided by 3 we get the answer is 60 to check the answer if we add angle A and Angle B is double angle C

Answer 2

Answer:

Angles are 72, 72 and 36.

Step-by-step explanation:

Let the third angle be x. Then, each of the equal angles are 2x and 2x.

By angle-sum property,

2x + 2x + x = 180

5x = 180

x = 36

2x = 72

So, the angles of the triangle are 72, 72 and 36.
