9. m of ABD if m of ABD = (6x + 4) and m of DBU 10. m of ABC if m of ABD = (5y - 3)" and m of DBC = (3y + 15)

Ray BD bisects ∠ABC so that m∠ABD = 5y – 3 and m∠CBD = 2y +12.

Find the value of y.

bisect" means to cut into equal parts.

Thus: 5y – 3 = 2y +12

#2 , let the endpoint be (x,y)

for the x:

(4+x)/2 = 2

4+x = 4

x = 0

for the y:

---- your turn

#3, just use your "distance between 2 points" formula
