Question

please help me and solve it with full explanation and solution​

Answer 1

Answer:

This problem is actually a system of equations.  Angle A and B being complementary gives us the following equation (A + B = 90).  This goes along with the second equation the difference of Angle A and B is 20 degrees (A - B = 20)

A + B = 90

A -  B = 20

Adding the two equations yields the following:

2A = 110

A = 55

Substituting back into the first equation:

55 + B = 90

B = 90 - 55

B = 35

The final step is substitute your answers for A & B into both equations to make sure they are both correct.

55 + 35 = 90

55  - 35 = 20

The smaller angle is 35 degrees

Answer 2

Answer:

ok I will try

complementary angles are

A + B = 90

A = 90 - B

and given

A+ B = 20

90 - B + B = 20
