Look at the information below. The sum of the measures of angle M and angle R is 90°. © The measure of angle M is (5x + 10). The measure of angle R is 55º. Write an equation that can be used to determine the value of x?

Answer:
Solution given;
<M=5x+10
<R=55
<M+<R=90°
5x+10+55=90°[is a required equation]
now solving it
5x=90-65
5x=25
x=25/5
x=5is your answer.
