Question

1 When an angle is added to three times its compliment then the sum is 230° , what will be the supplement of the given angle ?

Answer 1

Answer:

160

Step-by-step explanation:

Let the angle be = x

It's compliment = 90 - x

==: x + 3 (90 - x) = 230

==: x + 270 - 3x = 230

==: 2x = 40

==: x = 20

Angle = x = 20

Supplementary angle = 180 - x

                                    = 180 - 20

                                    = 160

Answer 2

Let the angle be x degrees.
Complement of x = (90-x) degrees
ATQ, x+3(90-x)=230
x+270-3x=230
x-3x=230-270
-2x=-40
x=-40/-2
x=20
Therefore, the angle is 20 degrees.
Supplement of this angle= 180-20
= 160 degrees
