Question

Each of two equal angles of an isosceles triangle is four times the third angle Find all the angles

Answer 1

$\green{ \bf\huge{ Answer }}$

Let's 1 angle = x

other two angles = 4x

Sum of angle in triangle = 180°

x + 4x + 4x = 180

9x = 180

x = 20°

one angle is 20° and other two angles are 80° and 80°

Answer 2

Answer:

Step-by-step explanation:

Each equal angle is 4btimes the third

Sum of all angle of A triangle=180°

4x+4x+x=180°

9x=180°

x=180÷9

x=20

First angle=4 X 20=80°

Second angle=4 X 20=80°

Third angle =20 X 1=20°
