Question

the angle of a traingke are (2x-7), (x+25) and (3x+12). find the measure of the angles​

Answer 1

Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.

(2x-7)+(x+25)+(3x+12)=180

6x+30 = 180

6x=150

x=25

Therefore, the angles are 43⁰, 50⁰, 87⁰

Answer 2

As we know , the sum of the angles of a triangle is 180 °

2x-7 + x + 25 + 3x + 12 = 180

6x + 30 = 180

6x = 180 - 30

6x = 150

x = 25

So , the angles are ,

= 2(25)-7

= 50 - 7

= 43°

= 25 + 25

= 50°

= 3(25) + 12

= 75 + 12

= 87°
