Answer:
the other two sides are 31.11 feet and 31.11 feet
Step-by-step explanation:
since two angles are 50°, the triangle is isosceles with the other two sides being equal in length.
A right triangle is formed by a line from its peak down & perpendicular to
the 40 foot side. It's hypotenuse is the unknown (x) and it's base is 40/2 = 20 feet.
cos 50 = 20/x
0.6428 = 20/x
x = 31.11 feet

Answer:
Step-by-step explanation:
For f(2), the input of the function is 2.
Let x = 2.
Evaluate.
The value of F(G(x)) is 2x^2 - 13
<h3>How to solve the composite functions?</h3>
The functions are given as:
F(x)=2x+1
G(x)=x^2-7
To find (FxG)(x), we make use of
(FxG)(x) = F(G(x))
So, we have:
F(G(x))=2G(x)+1
Substitute G(x)=x^2-7
F(G(x))=2(x^2-7)+1
Expand
F(G(x))=2x^2 - 14 + 1
Evaluate the like terms
F(G(x))=2x^2 - 13
Hence, the value of F(G(x)) is 2x^2 - 13
