U2LT9: Angle Bisector Theorem

• 22

• 44

• 11

• 68

• not enough information given

Answer explanation

"bisects" means that it makes two EQUAL angles, so if one part is 22, then the other part is also 22!

Solve for x.

• 7.4

Answer explanation

Remember, the dashes mean the angles are equal, so the equation would be:

5x+11=26

Angle ABC measures 34^o. What is the measure of angle CBD?

• 17^o

• 34^o

• 68^o

The measure of angle ABD is 74^o. What is the measure of angle CBD?

• 148^o

• 74^o

• 37^o

The measure of angle DBC is 14^o. What is the measure of angle DBA?

• 7^o

• 14^o

• 28^o

• m∠GHK=80.5,

  m∠KHJ=161

• m∠GHK=161,

  m∠KHJ=80.5

• m∠GHK=80.5,

  m∠KHJ=80.5

• m∠GHK=161,

  m∠KHJ=161

AND find the measure of ∠ABD

• x=3/17 ∠ABD = 27°

• x=9 ∠ABD = 81°

• x=3 ∠ABD = 27°

• x= -3 ∠ABD = -27°
