Answer:
0.7453
Step-by-step explanation:

(gof)(3) = g(f(3))
so
f(3) = -2(3) + 8 = 2
g(f(3)) = 5(2) = 10
answer
C. 10
Answer:
Option B

Step-by-step explanation:
we know that
The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite
so
![m\angle PTR=\frac{1}{2}[arc\ PR+arc\ QS]](https://tex.z-dn.net/?f=m%5Cangle%20PTR%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20PR%2Barc%5C%20QS%5D)
substitute the given values
![m\angle PTR=\frac{1}{2}[140^o+106^o]](https://tex.z-dn.net/?f=m%5Cangle%20PTR%3D%5Cfrac%7B1%7D%7B2%7D%5B140%5Eo%2B106%5Eo%5D)
