If $\overrightarrow{KM}$ bisects $\angle LKJ$ and $m\angle JKM=22\degree$ find $m\angle LKM$ .

not enough information given

m∠GHK=90, m∠KHJ=45

m∠GHK=45, m∠KHJ=45

m∠GHK=45, m∠KHJ=90

m∠GHK=90, m∠KHJ=90

Suppose the given figure is changed such that AC is an angle bisector and the m∠BAC = 38.

What would be the m∠BAD ?

142

In the figure, BA and BC are opposite rays.

BH bisects ∠EBC.

If m∠EBH = 6x-20 and m∠HBC = 8x-30, then which of the following is the correct equation to find the value of x?

6x-20 = 8x-30

2(6x-20) = 8x-30

6x-20 = 2(8x-30)

In the figure, BA and BC are opposite rays.

BH bisects ∠EBC.

If m∠EBC = 31a-2 and m∠EBH = 4a+45, then which of the following is the correct equation to find the value of x?

2(4a+45) = 31a-2

4a+45 = 31a-2

4a+45 = 2(31a-2)

In the figure, BA and BC are opposite rays.

BE bisects ∠ABF.

If m∠ABE = 2n+7 and m∠EBF = 4n-13, then which of the following is the correct equation to find the value of x?

2n+7 = 4n-13

2(2n+7) = 4n-13

2n+7 = 2(4n-13)

In the figure, BA and BC are opposite rays.

BE bisects ∠ABF.

If m∠ABF = 7b-24 and m∠ABE = 2b, then which of the following is the correct equation to find the value of x?

7b-24 = 4b

7b-24 = 2b

2(7b-24) = 2b

10.

In the figure, BA and BC are opposite rays.

BE bisects ∠ABF.

If m∠ABE = 2s+22 and m∠ABF = 8s-6, then which of the following is the correct equation to find the value of x?

2(2s+22) = 8s-6

2s+22 = 2(8s-6)

2s+22 = 8s-6

11.

In the figure, BA and BC are opposite rays.

BE bisects ∠ABF.

If m∠ABE = 5x+9 and m∠EBF = 4x+8, find the value of x.

x = -1

x = 1

x = -1.666

x = -2.333

14.

In the figure, XA and XE are opposite rays and ∠AXC is bisected by XB. Find the value of x and then find the m∠AXC if m∠AXC = 8x-7 and m∠AXB = 3x+10.

x = 13.5 ------------- m∠AXC = 101

x = 13.5 ------------- m∠AXC = 50.5

x = 3.4 ------------- m∠AXC = 20.2

x = 3.4 ------------- m∠AXC = 40.4
