Question

Two supplementary angles are (2x - 5) and (7x + 5), find the angles. Find the angles ​

Answer 1

Answer :-

Given,

• First supplement angle = (2x - 5)
• Second supplementary angle = ( 7x + 5)

We know that,

• Sum of supplementary angles = 180°

Therefore,

=> (2x - 5) + (7x + 5) = 180°

=> 9x + 5 - 5 = 180°

=> 9x = 180°

=> x = 180°/9 = 20°

So, first supplementary angle

=> 2x - 5

=> 2 x 20 - 5

=> 40° - 5

=> 35°

And,second Supplementary angle,

=> 7x + 5

=> 7 x 20 + 5

=> 140° + 5

=> 145°

Hope the answer helps you.
