Likurg_2 [28]3 years ago

Answer:

\large \boxed{41^{\circ}}

Step-by-step explanation:

     ∠1 = ∠2

    ∠3 = ∠4

∠JKN = ∠1 + ∠2 = 8x + 2

∠MKN = ∠3

∠MKL = ∠4 = 3x + 5

So, ∠3 = 3x + 5

\begin{array}{rcll}(\angle 1 + \angle 2) + \angle 3 + \angle 4 & = & 180 & \text{$\vec{KJ}$ and $\vec{KL}$ are opposite rays}\\8x + 2 + 3x + 5 + 3x + 5 & = & 180 & \text{Made the substitutions}\\14x + 12 & = & 180 & \text{Simplified}\\14x & = & 168 &\text{Subtracted 12 from each side}\\x & =  & \mathbf{12} & \text{Divided each side by 14}\\\angle3 & =  & 3x + 5 & \\& =  & 3(12) + 5 & \\& =  & 36 + 5 & \\& =  & \mathbf{41} & \\\end{array}\\m\angle MKN = \large \boxed{\mathbf{41^{\circ}}}

9. x=22

10. x=12

Step-by-step explanation:

1. RS/WS=ST/SX and m<RST=m<WSX

2. AB/PQ=8/6=4/3

BC/QR=AC/PR=12/9=4/3

AB/PQ=BC/QR=AC/PR

3. ST/JP=10/15=2/3

SU/JM=14/21=2/3

ST/JP=2/3=SU/JM

and m<TSU=70°=m<PJM

4. DK/PR=8/4=2

JK/ZR=18/9=2

DK/PR=2=JK/ZR

and m<DKJ=65°=m<PRZ

5. RT/ST=UT/LT

and m<RTU=m<STL

6. KL/YW=20/18=10/9

JL/XW=36/24=3/2

KL/YW=10/9≠3/2=JL/XW

7. BF/NL=24/16=3/2

BE/NM=39/26=3/2

BF/NL=3/2=BE/NM

and m<EBF=m<MNL

8. GH/QR=32/20=8/5

HI/RS=40/25=8/5

GI/QS=24/15=8/5

GH/QR=HI/RS=GI/QS=8/5

9. x/33=18/27

Simplifying the fraction on the right side of the equation:

x/33=2/3

Solving for x: Multiplying both sides of the equation by 33:

33(x/33)=33(2/3)

x=11(2)

x=22

10. x/16=9/12

Simplifying the fraction on the right side of the equation:

x/16=3/4

Solving for x: Multiplying both sides of the equation by 16:

16(x/16)=16(3/4)

x=4(3)

x=12
