Answer:

x = 12
Step-by-step explanation:
The slope-intercept form formula,
, can be used to write an equation for the line.
Where,
m = slope = 
b = y-intercept, which is the point at which the line intercepts the y-axis. At this point, x = 0.
Let's find the slope (m) using the coordinates of the two points given, (0, 30), (3, 60).

Let,





y-intercept of the line, b = 30
Equation for the line would be:

Using the equation, find x when y = 150.
Simply substitute the value for y in the equation to find x.

Subtract 30 from both sides


Divide both sides by 10


x = 12

![18 {u}^{2} - 50y \\ \\ = 2[9 {u}^{2} - 25y] \\ \\ = 2[(3 {u})^{2} - (5 \sqrt{y} )^{2} ] \\ \\ = 2(3u + 5 \sqrt{y} )(3u - 5 \sqrt{y} )](https://tex.z-dn.net/?f=18%20%7Bu%7D%5E%7B2%7D%20%20-%2050y%20%5C%5C%20%20%5C%5C%20%20%3D%202%5B9%20%7Bu%7D%5E%7B2%7D%20%20-%2025y%5D%20%20%5C%5C%20%20%5C%5C%20%20%3D%202%5B%283%20%7Bu%7D%29%5E%7B2%7D%20%20-%20%285%20%5Csqrt%7By%7D%20%29%5E%7B2%7D%20%5D%20%20%20%5C%5C%20%20%5C%5C%20%20%3D%202%283u%20%20%2B%205%20%5Csqrt%7By%7D%20%29%283u%20-%205%20%5Csqrt%7By%7D%20%29)
Using complementary angles, <X is equal to <Z, so it's <Z = 35°.
