Question

the angles of triangle are (x+5) degree, (x+10) degree and (x+15) degree. make and equation and find the value of x, then find the actual sizes of the angles

Answer 1

Answer:

50=x angles are 55 60 65 respectively

Step-by-step explanation:

as we know sum of all angle of triangle is 180

therfore

(x+5)+(x+10)+(x+15)=180

3x+30=180

3x=180-30

x=150/3

x=50

1st angle= 50+5=55

2nd angle=50+10=60

3rd angle=50+15=65
