Answer:
B
Step-by-step explanation:
We know that, in total, a straight line always adds up to 180°. So, to combine these two angles, 4x and 2x, that would mean that 6x equals 180°
So, to find x, divide 180 by 6.
180/6=30
X=30
The desired angle is 2x. So, plug 30 in for x.
2(30)=60
So, angle YXZ is 60°
