In a triangle, the sum of all angles is always 180°. If two angles measure 90° and 61°, you can find the measure of the third angle by subtracting the sum of the known angles from 180°.
Here’s how to calculate it step-by-step:
1. Add the two known angles:
( 90° + 61° = 151° )
2. Subtract this sum from 180° to find the third angle:
( 180° – 151° = 29° )
So, the measure of the third angle is 29°.
In a triangle, the sum of all three angles is always 180°. If two angles measure 90° and 61°, you can find the measure of the third angle by subtracting the sum of the known angles from 180°.
1. Calculate the sum of the known angles:
( 90° + 61° = 151° )
2. Subtract this sum from 180° to find the third angle:
( 180° – 151° = 29° )
Thus, the measure of the third angle is 29°.
