Question

if the angle of a triangle (2x) °. (3 X + 5 )and (4 x - 14) ° then the measure of the angle respectively are​

Answer 1

Answer:

sum of angleof triangle=180°

2x+(3x+5)+(4x-14)=180°

9x-9=180°

9x=180+9

x=189/9

x=21

so

1st angle=2×21=42°

2nd. angle=3×21+5=68°

3rd angle=4×21-14=70° Ans
