Question

sum of three angles X degree X + 50 degree and X + 70 degree is 180 degree find the angles​

Answer 1

Answer:

X+X+50+X+70=180

3x+120=180

3x=180-120

3x=60

x=60/3

x=20.

so first angle is 20,second angle is X+50(20+50=70) and third angle is X+70(20+70=90)

Answer 2

Answer:

Step-by-step explanation:

As per angle sum property of a triangle

angle 1 + angle 2 + angle 3 =180°

Hence

X + X +50 °+ X + 70° = 180"

3X + 120 = 180°

3X= 180°-120°

3X = 60

X =60/3 = 20

Hence angles are

X = 20°

X+50= 20+50 =70°

X +70= 20+ 70 =90 °

Hope it is clear
