All triangles have 180o in them when the 3 angles making them up are added together.
Givens
F = 90
E = 29
D = ???
Equation
<D + <E + <F = 180
Substitute and solve
<D + 90 + 29 = 180
<D + 119 = 180
<D = 180 - 119
<D = 61

Well if you divide 7 divided by 12 you get 0.583 which you can round however you wish but I am not sure if that’s what you mean
Answer:
Step-by-step explanation:
Charging by the quarter mile is for purpose of making that particular taxi service seem cheaper than the others when they post a per mile charge. If this taxi company is charging .50 per 1/4 mile, they are charging $2 per mile. So we will base our equation on the per mile charge, not the per quarter-mile charge. If x is the number of mile driven (our uknown), and we have a flat fee of $2.50 regardless of how many miles we are driven, the cost function in terms of miles is
C(x) = 2x + 2.50
If we are driven 5 miles, then
C(5) = 2(5) + 2.50 so
C(5) = 10 + 2.50 and
C(5) = $12.50
It would cost $12.50 to be driven 5 miles
