Answer:

x=50

Step-by-step explanation:

angles in a triangle add up to 180 degrees

hence, 50 + 2x + 30 = 180

solving for x

50 + 2x + 30 = 180  

combine like terms

2x + 80 = 180

subtract 180 from both sides

2x = 100

divide both sides by 2

x = 50

Answer:

x=50

Step-by-step explanation:

50°+30°+2x = 180° (sum of all angles of a triangle)

or, 2x +80°= 180°

or, 2x = 180°-80°

or, 2x=100°

or, x= 100°/2

therefore,x°=50°

Again,

2x = 2×50°=100°
