If two angles are supplementary, then
the sum of their measures is 180°.
So if the measure of an angle is 77°,
the measure of its supplement is 103°.
We can find the measure of its supplement by taking 180 minus the measure of the original angle which in this case is 180 - 77 or 103°.

Answer:
360 miles
Step-by-step explanation:
Every half inch on the map equal 45 miles on the highway. Find out how many half-inches there are in 4 inches, and multiply that by 45 to get the answer.
To do this, first divide 4 by 0.5
4/0.5 = 4/(1/2) = 4(2/1) = 8
There 8 half-inches in 4 inches
**Also think that there are 2 halves in 1, so in 4 there are 2(4) halves, which is 8
Now take 8 and multiply by 45
8(45) = 360
The highway is 360 miles long
