Answer:
20
Step-by-step explanation:
point slope form is y=mx+ b
m is slope which is given as 1/2
replace x & y into the equation to solve for b
b = 6
so equation is y =1/2x+6
Answer:
YZ=16
Explanation:
XWY=20 XWZ=40, XWY is half of XWZ, which means ZWY =20. Now you can say that the triangles are congruent through the AAS postulate, so you know that YZ-16 because of CPCTC
