By the process of elimination I believe that the angle the sun makes with the building is the vertex angle. If that is our reference angle, we have the hypotenuse as 150 and we are looking for the side opposite the reference angle, which we will call x. Therefore, the sin ratio is the one we need, as sin is equal to the side opposite over the hypotenuse.
and 150 sin(75) = x. That gives you an x value of 144.89, first choice above.

Answer:
y = 6x +1
Step-by-step explanation:
To write the slope-intercept form equation for a line, you need to know the slope and the y-intercept. These can be found from their respective formulas.
__
<h3>slope</h3>
The slope of a line between points (x1, y1) and (x2, y2) is given by the formula ...
m = (y2 -y1)/(x2 -x1)
For points (-1, -5) and (0, 1), the slope is ...
m = (1 -(-5))/(0 -(-1)) = 6/1
m = 6
<h3>y-intercept</h3>
The y-intercept is the value of y where the line crosses the y-axis. That axis is where x = 0. There is a formula that can be used to find the y-intercept from the slope and a point on the line:
b = y -mx . . . . . y-intercept of line with slope m through point (x, y)
However, one of the given points is already the y-intercept: (0, 1). It tells you b=1.
<h3>equation</h3>
The slope-intercept equation is ...
y = mx +b
y = 6x +1
880 m^2 is the surface area
