Answer:
Step-by-step explanation:
The graph shows the function value is zero for x=5 and x=7. These are the elements of the solution set.
x ∈ {5, 7}
__
The graph is below the x-axis between these points, so that is the region where f(x) < 0
5 < x < 7 . . . . . for f(x) < 0
In interval notation: (5, 7).
50% of 30 is 15.
30% of 10 is 3
f(6)
38°
![m\angle 4 = 180° - [62\degree + (62\degree + 18\degree)] \\\\m\angle 4 = 180\degree - [62\degree + 80\degree] \\\\m\angle 4 = 180\degree -142\degree \\\\m\angle 4 = 38\degree \\\\](https://tex.z-dn.net/?f=m%5Cangle%204%20%3D%20180%C2%B0%20-%20%5B62%5Cdegree%20%2B%20%2862%5Cdegree%20%2B%2018%5Cdegree%29%5D%20%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3Em%5Cangle%204%20%3D%20180%5Cdegree%20-%20%5B62%5Cdegree%20%2B%2080%5Cdegree%5D%20%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3Em%5Cangle%204%20%3D%20180%5Cdegree%20-142%5Cdegree%20%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3Em%5Cangle%204%20%3D%2038%5Cdegree%20%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E)
