Answer:
The angle of elevation is 71.94 degrees.
Step-by-step explanation:
We are given the following in the question:
The front of an A-frame cottage has the shape of an isosceles triangle.
Height,h = 23 feet
Base,b = 15 feet
We have to find the angle of elevation of its roof.
The attached image shows the structure.
We use the relation,

Thus, the angle of elevation is 71.94 degrees.

F(n) = n + 3
f(n) = -(n + 3)
f(n)= n -3
Answer:
2, 3
Step-by-step explanation:
If the first integer is x, then the second is x+1. The given relation is ...
x +3(x+1) = 11
4x = 8 . . . . . . . . subtract 3
x = 2 . . . . . . . divide by 4
The integers are 2 and 3.

2 + 3(3) = 2+9 = 11
Answer:
x = -8 and x = -4.
Step-by-step explanation:
1/(x + 3) = (x + 10)/(x - 2)
1 * (x - 2) = (x + 10) * (x + 3)
x - 2 = x^2 + 3x + 10x + 30
0 = x^2 + 13x + 30 - x + 2
0 = x^2 + 12x + 32
0 = (x + 8) * (x + 4)
1. x = -8
2. x = -4
The correct result would be x = -8 and x = -4.
