<h2><u>Question</u> :</h2>
The sum of the measure of angle M and angle R is 90°.
- The measure of angle m is (5x + 10)°.
- The measure of angle R is 55°.
What is the value of x?
<h2><u>Answer</u> :</h2>- The value of x is 5°
- ∠M + ∠R = 90°
- ∠M = (5x + 10)°
- ∠R = 55°
- Value of x = ?
We are given :
- ∠M + ∠R = 90°
- Value of ∠M = (5x + 10)°
- Value of ∠R = 55°
So, by substituting value of ∠M and ∠R in ∠M + ∠R = 90°, we have :
Hence, value of x is 5°.
