Step-by-step explanation:
The question missing attachment (incomplete)
But the question said how far up does the ladder reach on the building?
See the attachment
Let the tita be 60° and the height of the building be 50 meters
Now
Opposite/hypotenuse = sin(tita)
50/x = sin60°
Cross multiply to find x
x = 50/sin(60°)
x= 50/0.8660
x=57.7 meters
Answer:
22/7
Step-by-step explanation:
22/7 is not very close to pi, but it is sometimes used as an estimation for pi
Answer:
<h2>
y = (5/2)x + 5/2</h2>
Step-by-step explanation:
The coordinates of the given x-intercept are (-1, 0).
As we move to the right from (-1, 0) to (2. 7.5), x increases by 3 and y by 7.5.
Thus, the slope of this line is m = rise / run = 7.5 / 3, or 75 / 30, or 5/2.
Thus, starting from y = mx + b, we have:
7.5 = (5/2)(2) + b, or
7.5 = 5 + b
Thus, b = 2.5, and the equation is
y = (5/2)x + 5/2
check: Is 7.5 = (5/2)(2) + 5/2 true?
Is 7.5 = 5 + 5/2 true? YES
Answer:
I can't draw the graph but the notation is: 
x equals to all the region in the left from -7.09689...
