Question

Tivo supplementary angles are (2x - 5)" and (7x + 5)", find the angles please guys tell me​

Answer 1

ANSWER : 35° and 145°

We know, supplementary angles are the angles whose sum is 180°

So, According to question,

2x-5+7x+5=180

= 7x+5x+0=180

9x =180-0

9x=180

x =180/9

x =20

Now,putting the value of x in 2x-5,

First supplement angle = 2(20)-5 =40-5= 35°

Now, putting the value of x in 7x+5

2nd supplement angle = 7(20)+5=140-5=135°

Therefore, the two supplementary angles are 35° and 145°

HAVE A NICE DAY!

Answer 2

Step-by-step explanation:

2x-5+7x+5=180

9x-5+5=180

9x=180

x=180/9

x=20

2x+5=2×20-5=35

7x+5=7×20+5=145
