The two angles of a right-angled triangle, one is double the other. Find the angles​

Answer»

WER--

We KNOW that one angle is 90

Lets take another angle as= x

Now it is GIVEN in the question that one angle is double the other, so it would be 2x

Now we know that sum of all the ANGLES of a TRIANGLE is equal to 180.

The equation will be formed as-  90+2x+x=180

2x+x= 3x

so 90+3x=180

3x=180-90

3x=90

x=90/3

x=30

so one angle is 30.

second was double of it, so 30 multiply 2, 60

ANS- 90, 60, 30 are the angles of the triangle, and if you want to check add these angles. 90+60+30

90+90= 180, it is correct

I hope it HELPS
