Question: Example 27. Rays BA and BC are perpendicular. Point D lies in the interior of LABC. If mLABD=(3r+ 5) andm2DBC= (5r - 27), find m2ABD

Example 27. Rays BA and BC are perpendicular. Point D lies in the interior of LABC. If mLABD=(3r+ 5) andm2DBC= (5r - 27), find m2ABD and mDBC.8. WX and YZ intersect at point V. If m2WVY = (40 + 58) and m2XVY = (26 - 18)9, find the valuesof a and b such that WX is perpendicular to YZ9. Refer to the figure at the right. If m42 = (a + 15)9 and m43 = (a35)9, find the value of a so that HI 1 H).10. Rays DA and DC are perpendicular. Point B lies in the interior ofLADC. If mLADB - (3a + 10) and m2BDC = 13a, find a, mLADB,and mABDC.

mple 2 Rays BA and BC are perpendicular. Point D lies in the interior of ZABC. If maABD = (3r + 5) ar mZDBC = (5r - 27)", find mcABD and m/DBC
