Use the diagram below to answer the question. find the m< c part a) identify what allowed you to set up an equation to solve for x part b) solve for x part c) find m< c

Line BD is perpendicular to line AC. both angles ADB and CDB are right angles.

4x+10=90
subtract 10 from both sides

4x=80
divide both sides by 4 to isolate x

x=20

plug in 20 for x in the equation (x+11) to find the measure of angle c

20+11=31°

the measure if angle c is 30°

No i don,t argee because a factor is a bunch of numbers and a divisor is a part of a division problem
