The sum of the measures of angle m and r are complemetary. the measure of the angle m is (5×+90). the measre of angle r is 55. what is the value of x?

The value of x is - 11  

Step-by-step explanation:

Given as :

∠ M = (5x +90) °

∠ R = 55°

The sum of measure of angle M and R are complementary

Complementary Angle are those when sum of two angle equal to 90°

∵ Angle M and R are complementary in nature

∴ ∠ M + ∠ R =  90°

Or, (5x +90) ° + 55°  =  90°

Or, 5x = 90° - 90°  - 55°  

Or, 5x = - 55°

∴      x = - = - 11

Hence the value of x is - 11        Answer
