Question

5. THE THREE ANGLES OF A TRIANGLE ARE IN THE RATIO 1:2:1. FIND ALL
THE ANGLES OF THE TRIANGLE.​

Answer 1

Answer:

Let the angles be 1x,2x&1x

then,

1x+2x+1x=180(Angle sum property)

4x=180

x=180/4

x= 45

So the angles are,

1x=1*45=45°

2x=2*45=90°

1x=1*45=45°

The angles are 45°;90°;45°

Answer 2

Answer:

1:2:1 = 45:90:45

Step-by-step explanation:

Three sides of triangle = 180

1:2:1 = x :2x:x

x + 2x + x = 180

4x = 180

x = 180/4

x = 45

x = 45

2x = 2 x 45

=90

x = 45
