Question

Q14) If ( 3x + 5)º And (2x - 25 )° is a pair of linear angle. Find the value of 'x'.​

Answer 1

sum of pair of linear angles is 180

so, (3x+5)+(2x-25)=180

5x-20=180

5X=200

X=200/5

X=40°

please mark as brainliest.

Answer 2

Answer:

x=40 degrees

Step-by-step explanation:

(3x+5)+(2x-25)=180(a linear pair includes two supplementary angles whose sum is 180 degrees)

=> 3x+5+2x-25=180

=>5x-20=180

=>5x=180+20

=>5x=200

=>x=200/5

=>x=40
