Pythagorean theorm is( hypotenuse)^2=(base)^2+(perpendicular)^2
(18)^2-(9)^2=x^2
x=15.58
Answer:
x=16
Step-by-step explanation:
The opposite angles will always be supplementary
<K + < M = 180
47+ 7x+21 = 180
Combine like terms
7x+68 = 180
Subtract 68
7x = 180-68
7x = 112
Divide by 7
7x/7 = 116/7
x =16
For the distance from nikos home to the library, the distance on the map should be
4/6th of an inch

First, find the value of g(x) at x=4: it's 3.
Next, use this result, 3, as the input to f(x): f(3) = 1
So f(g(4)) = 1.
