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°
