Hi there!
Angles that are complementary add up to 90. We know that in order to find the value of x, we'll need to create an equation. This equation would be (x + 15) + 48 = 90. This is because, together, the two angles must add up to 90.
ANSWER:
D - (x + 15) + 48 = 90
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Step-by-step explanation:
First thing first, let find the x value of where P and Q both meet y=5, we know that y=5, and y=2x^2+7x-4, so using transitive law,
Now, to find the gradient of the curve let take the derivative of both sides
Plug in -9/2, let call that point P
Plug in 1, let call that point Q
So the gradient of the curve at point P (-9/2,5) is -11
The gradient of the curve at point Q (1,5) is 11.
4x+1/3=x-5/2
4x-x=-5/2-1/3
3x=-17/6
1/3(3x)=1/3(-17/6)
X=-17/18
