really?
5x+10 + 55 = 90
To find the value of x, we can use the given information that the sum of the measures of angle M and angle R is 90°.
According to the information given, the measure of angle M is (5x + 10)° and the measure of angle R is 55°.
So, we can set up the equation:
(5x + 10) + 55 = 90
Now, let's solve this equation to find the value of x:
Combine like terms: 5x + 65 = 90
Subtract 65 from both sides of the equation: 5x = 90 - 65
Simplify: 5x = 25
Divide both sides of the equation by 5: x = 25/5
Simplify: x = 5
Therefore, the value of x is 5.
