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.
