Answer:
The answer is 125
Step-by-step explanation:
So you have m∠ZWY=43° and m∠XYW=12°. You would first take those two numbers and times them by two. It should look like this:
43(2) and 12(2)
Which gives 86 and 24
Next you would add (2)m∠WXY plus 86 and 24 which would equal 360.
(You times (2)m∠WXY because we times 2 by the other numbers)
It should look like this:
(2)m∠WXY + 86 + 24= 360
Next solve equation to find m∠WXY. It's just like trying to find x.
(2)m∠WXY + 86 + 24= 360
(2)m∠WXY + 110= 360
minus 110 on both side of the equation
(2)m∠WXY + 110-110= 360-110
(2)m∠WXY = 250
now divide 2 on both sides and you get 125.
