Question

12. Two angles of a triangle are in the ratio 1:2. If the
sum of these angles is equal to the third angle, find​

Answer 1

Answer:

find what

60 first angle

120 second

180 third angle

Step-by-step explanation:

1:2:3=360

1/6 * 360 = 60

Answer 2

Answer:

Let the sum of the two angles be x and 2x resp....

Then the measure of the third angle= 3x

Therefore,

A/Q,

x+2x+3x=180

6x=180

x=30

So,

First angle=30°

second angle=60°

third angle=90°
