Question

Find The measure of the angle if it is 70 degree less than three times its complementary angles..(4marks)

Answer 1

Answer:

So let one angle be x.

So other is 3x-70.

Both are complementary {90°}

So x+3x-70=90°

4x-70=90

4x=160

x=40°

So other is

3x-70=3(40)-70=120-70=50°

So the two angles are 40° and 50°

Answer 2

Answer:

let one angle be x

so the other angle according to question is

3x-70

they are complementary

so

=>x+3x-70 = 90

=>4x = 90+70

=>x = 160/4

=> x = 40°

so the other is 3x-70 = 120-70 = 50°
