In △XYZ, angle X is the smallest angle, angle Y is 40 degrees more than angle X, and angle Z is 2 times the measure of angle X. What is the measure of angle X?

x=35°   y= 75°   z = 70°

Step-by-step explanation:

Y = x+40   (known)

z = 2x    (known)

x + y + z = 180     (triangle property)

x + (x+40) + 2x = 180   (substitution)

4x + 40 = 180

4x = 140

x = 35

y = x + 40 = 75

z = 2x = 70

i dont know sorry

step-by-step explanation:

i think the correct option is the second option.
