Answer:
(f•g)(5)=
Step-by-step explanation:
f(x) =1/2x + 7
g (x) = 6x -8
f(g(5))
f(22)=+7
= +7
=

The sum of the interior angles of a triangle is 180 degrees.
1.) Translating the problem into equation:
7:11:12 = 180 degrees
7x+11x+12x = 180 degrees; Where x = missing number
30x = 180
30x/30 = 180/30 divide both sides by 30
x = 6
2.) Substitute the values:
7x+11x+12x = 180
7(6)+11(6)+12(6) = 180
42+66+72 = 180
180 = 180
3.) Therefore, the angles should be 42 degrees, 66 degrees and 72 degrees.
4.) See attached drawing of triangle

Answer:
12. 37. 13. 48 14. 75. For 15-17 just do the two angles equal to each other. for example (5x-17)=(3x-14) and find x. Same with 7 and 8
I'll show you how to do the first one.
