the answer is A but im just guessing ya know?
Answer:
60
Step-by-step explanation:
The corresponding angles of the triangles are given, y + 10 and 2y - 40. You need to first find the value of the variable (in this case, y), and to do this, you need to set them equal to one another:
y + 10 = 2y - 40
<u>Subtract y from both sides:</u>
<u />
y + 10 = 2y - 40
-y -y
____________
10 = y - 40
<u>Add 40 to both sides:</u>
<u />
10 = y - 40
+40 +40
________
50 = y
Now that we have the value of y, you need to plug the value into one of the expressions (either one will come out with the same answer):
y + 10
50 + 10 = 60
<em><u>OR</u></em>
<u />
2y - 40
2(50) - 40
100 - 40 = 60
<u />
For some reason, the value of "w" is not supplemented into the equation, which is weird, but whatever. I will answer the problem for you.
The answer you are looking for is -5.
Solution/Explanation:
Writing out the expression first
-7/3x+y²
Substituting the given values of the variables, only "x" and "y"
-7/3(6)+(-3)²
Simplifying
(-7/3)(6)=-14
(-3)²=9
So, we will come up with -14+9.
This simplifies to -5.
So, therefore, the final answer to this problem is -5.
Hope this helped answer your question for you. Good day to you.
