=> 22+10x
=> 2(5x+11)
This is the answer for your question
1. X-3=13 X=16
2. 45/9=5 M=5
3. 18•6=108 108/6=18
4. 17+8=25
5. 7•4=28
6. 7•9=63 63/7=9
7. 12+20=32 32-12=20
8. Y=75 3•25=75
9. 1/5r=15 r=15•5 r=75
10. 2y-6=34 2•20=40 40-6=34 y=20 I think
11. N=4 4+5=9
12. 16+3=19
13. 30+7= 37 p=37
14. 75/15=5 15•5=75 k=5
Answer:
C. 
Step-by-step explanation:
We have been given a triangle. We are asked to find the measure of angle Z using Law of cosines.
Law of cosines: 
, where, a, b and c are sides opposite to angles A, B and C respectively.
Upon substituting our given values in law of cosines, we will get:
Now, we will use inverse cosine or arc-cos to solve for angle Z as:
Therefore, the measure of angle Z is approximately 51 degrees.
