Answer:
The measurement of angle A is: 77°
Step-by-step explanation:
First of all, let us define complementary angles
The angles whose sum is 90° are called complementary angles.
Given angles are:
m∠A = 6x+29
m∠B = x+5
With respect to the definition, the sum of both angles will be 90°
Writing this mathematically we get
Putting the value of x in the expression for angle A
Hence,
The measurement of angle A is: 77°
