Question

In the adjacent triangle ABC, find the value of x and calculate the measure of all the angles of the triangle ​

Answer 1

may be it's like that

x+15+x-15+X+30=180°

3x+30=180°

3x=180-30

X=150/3

so X=50

the measures of triangles are

X+15=50+15=65°

x-15=50-15=35°

X+30=50+30=80°

hope it helps you

Answer 2

Answer:

65° , 35° , 80°

Step-by-step explanation:

( x + 15 ) + ( x + 30) + ( x- 15) = 180°

                                        3x = 180° - 15 - 30 +15

                                             = 150°

                                         x = 150°/3  

                                             = 50°

if x = 50°............

BAC (x + 15) = 65°

ABC (x - 15) = 35°

ACB (x + 30) = 80°
