Use the figure to complete each statement. m cd is the ab ae = ½ if ab = 18, then eb =is the midpoint of

3.) 90°; perpendicular bisector; AB; 9; E, AB.

Step-by-step explanation:

∠BEC and ∠BED form a linear pair.  This means their sum is 180°.  Since we know that m∠BEC = 90°, this means that

m∠BED = 180-90 = 90°.

Since AE = AB and CD intersects AB at right angles, this means that CD is the perpendicular bisector of AB.

This means that AE = 1/2AB.

If AB = 18, then AE = 1/2(18) = 9.

3)

a. m<BED = 90°

b. CD is the perpendicular bisector of AB

c. AE is 1/2 AB (AE = EB)

d. If AB = 18 , then EB = 18/2 = 9

e. E is the midpoint of AB

Hope it helps.

answer: 60

step-by-step explanation:

1/2a + (2/3×30)   = 50

1/2a + 20 = 50

1/2a = 30

a = 60

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
