Question

Tell whether the angles are complementary or supplementary. Then find the value of x.

choices are:
Supplementary ; x = 5
Supplementary ; x = 25
Complementary ; x = 5
Complementary ; x = 25

Answer 1

Complementary;x= 5

Explanation:

Complementary angle of a right angle = 90°

therefore

65 + 5x = 90

5x = 90 - 65

5x = 25

5x/5 = 25/5

x = 5

hence the complementary angle of x = 5

Answer 2

Complementary angles form a right angle.

Complementary:

• 65 + 5x = 90

• 5x = 25

• x = 5
