Question

what is the answer ofthe following question that is marked with yellow colour and tell with solution
​

Answer 1

Answer:

123 and 57

Step-by-step explanation:

sum of supplementary angles is equal to 180

A/Q

we have

$= (12x + 27) +( 6x + 9) = 180 \\ = 18x + 36 = 180 \\ 18x = 180 - 36 \\ 18x = 144 \\ x = \frac{144}{8} = 8$

now,angles are

$= 12x + 27 \\ = 12 \times 8 + 27 \\ = 123$

$6x + 9 \\ = 6 \times 8 + 9 \\ = 48 + 9 \\ = 57$

please mark as brilliant if you like the solution.I need to reach ace❤️

Answer 2

Answer:

The Angles are 123° and 57°.

Step-by-step explanation:

We know that,

Supplementary Angles are Angles that add up to 180°.

Thus,

The Given Angles must add up to 180°

Then,

(12x + 27) + (6x + 9) = 180°

12x + 27 + 6x + 9 = 180°

18x + 36 = 180°

18x = 180 - 36

18x = 144

x = 144/18

x = 8

Then, The Angles are,

(12x + 27) = 12(8) + 27

= 96 + 27

= 123°

Also,

(6x + 9) = 6(8) + 9

= 48 + 9

= 57°

Hence,

The Angles are 123° and 57°.
