G(5) = 2(5)-5=5
h(2)=4(2)+5=13
So, g(5)+h(2)=13+5=18.
Half one is 1/2;
half three is 3/2;
Thus, if f(x) represents annual growth, f(x)/2 shows it every half-year, like this:

Written in plain text: f(x)=15/2*2^x
It would be 115
180-65 = 115 and 180 comes from the straight line which is half of 360
The answer for your question is B
Hello!
As you can see, the angles we are given make up a 90 degree angle. We have the equation below.
4x=90
To solve we just divide both sides by 4.
90/4=22.5
x=22.5
I hope this helps!
