Answer:
x = 47.4
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj / hyp
cos x = 8.8 / 13
Take the inverse cos of each side
cos ^-1 ( cos x) = cos ^-1( 8.8 /13)
x = cos ^-1( 8.8 /13)
x =47.39633319
Rounding to the nearest tenth
x =47.4
Answer:
3
Step-by-step explanation:
10:15=2:3
6:x=10:(15-10)=2:1
x=3
<u>Given </u>that the functions
and 
We need to determine the value of the function 
First, we shall determine the composition of the function 
<u>Function </u>
<u>:</u>
Let us determine the function 
Thus, we have;
![(g \circ f)(x)=g[f(x)]](https://tex.z-dn.net/?f=%28g%20%5Ccirc%20f%29%28x%29%3Dg%5Bf%28x%29%5D)
![=g[x+4]](https://tex.z-dn.net/?f=%3Dg%5Bx%2B4%5D)



Thus, the function is 
<u>Value of the function </u>
<u>:</u>
The value of the function can be determined by substituting x = -3 in the function 
Thus, we have;

Simplifying the terms, we get;



Thus, the value of the function
is 1.
