The value of y in the triangle is 6°.
<h3>How to calculate the value of y in the triangle?</h3>
Firstly, it's important to note that a triangle has the total angles of 180°.
Based on the information, the triangle has interior angle measures of 11y, 10y + 10°, and 10y - 16º.
The value of y in the triangle will be illustrated thus:
11y + 10y + 10 + 10y - 16 = 180
31y - 6 = 180
31y = 180 + 6.
31y = 186
Divide.
y = 186 / 31
y = 6
The value of y is 6.

F(4) = 4^2-5
f(4) = 4x4-5
f(4) = 16-5
f(4) = 11
Answer: (x, y) = (3, 4)
This is the same as saying x = 3 and y = 4 pair up together
======================================================
Explanation:
Subtract the equations straight down.
- The x terms subtract to 5x (because -5x-(-10x) = -5x+10x = 5x)
- The y terms subtract to 0 (because 2y-2y = 0)
- The right hand side values subtract to 15 (because -7-(-22) = -7+22 = 15)
After all that is said and done, we have this new equation
5x = 15
Divide both sides by 5 to get x = 3
Then we use this x value to find y
-5x+2y = -7
-5(3)+2y = -7
-15+2y = -7
2y = -7+15
2y = 8
y = 8/2
y = 4
Or,
-10x+2y = -22
-10(3)+2y = -22
-30+2y = -22
2y = -22+30
2y = 8
y = 8/2
y = 4
Either way, we end up with y = 4.
Overall, the solution as an ordered pair is (x, y) = (3, 4)
If you were to graph the two equations, they intersect at the location (3,4).
