Question

the supplement of a angle is 3 times the angle it self find the angle (who ans. the question correct I will mark as brainliest)​

Answer 1

Answer:

Let the angle to be solved be

x

Let the supplement/compliment by

y

x

+

y

=

90

Complimentary angles add up to 90 degrees.

x

+

3

y

=

180

Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.

Evaluating this as a system:

x

+

y

=

90

Isolate

x

:

x

=

90

−

y

Input into the other equation:

(

90

−

y

)

+

3

y

=

180

Combine like terms, isolate

y

and its coefficients:

2

y

=

90

Isolate

y

y

=

45

Input into the first equation:

x

+

45

=

90

Isolate

x

:

x

=

45

degrees

Answer 2

Answer:

x=45

Step-by-step explanation:

lets take the angle as x

then , according to the question

x+3x=180(supplemetary angles )

4x=180

x=180/4

x=45
