Answer:
The measure of angle x is 
Step-by-step explanation:
To find the measure of angle X, apply the law of cosines
The law of cosines states that

In this problem we have




substitute



![C=arccos[(986-576)/950]=64.4\°](https://tex.z-dn.net/?f=C%3Darccos%5B%28986-576%29%2F950%5D%3D64.4%5C%C2%B0)
Therefore
The measure of angle x is 
The answer is a. the first step is to divide the whole bottom equation by -1 because x can’t be negative. you then plug in y + 9 into the first equation to solve. so the equation would be (y + 9) + y = 11. you do this because in substitution you plug in one of the equations into the other equation. you then get 2y + 9= 11. you would next subtract 9 to both sides which leaves you with 2y= 2, divide by both sides, y = 1. you then plug the why value into the first equation to figure out the value for x. so it would be x + 1 = 11, subtract 1, x equals 10.
sorry this was hard to explain! hope this helps!
Answer:
its A I promise! good luck!
Answer:
<u>Yes</u>
Step-by-step explanation:
<u>When there are 2 rows</u>
- Number of erasers per row = No. of erasers / No. of rows
- Number of erasers per row = 18/2
- Number of erasers per row = 9
<u>When there are 3 rows</u>
- Number of erasers per row = No. of erasers / No. of rows
- Number of erasers per row = 18/3
- Number of erasers per row = 6
<u>Therefore, there will be more erasers per row in 2 equal rows than in 3 equal rows.</u>
