Question

two complementary angles are in the ratio 5:1. What are their measures?
one angle is thrice the other and the two angles are supplement to each other
then tind their measures.

Answer 1

Two angels are A, B
if A and B are complementary angels then

A +B =90

5x + x= 90

X = 15

1st angels 15
2nd angels 5x =5x15 =75










Now two angles are supplementary then



A + B = 180

A/c to question

A +3A = 180

A = 45

Another angle 3A =3x45 = 135













IF two angle are linear pair then A + B = 180


A/c to question

2x + 7x= 180

X=20

1st angle 2x = 2x20 = 40

Other angle 7x = 7x20 =140
