The answer is B. <span>$78.20; this is the amount Derek pays for 320 minutes of international calls.
Simply substitute in 320 wherever there is an x and solve. The problem also already told us that x stands for minutes so we know it is 320 minutes.</span>
Answer:
32
Step-by-step explanation:
A rule of polygons is that the sum<span> of the </span>exterior angles<span> always equals 360 degrees, but lets prove this for a regular </span>octagon<span> (8-sides). First we must figure out what </span>each<span>of the interior </span>angles<span> equal. To do this we use the </span>formula<span>: ((n-2)*180)/n where n is the number of sides of the polygon</span>
Answer:
24
Step-by-step explanation:
I learned this in like 5th grade
The angles of a triangle should add up to 180 degrees. in the left triangle, you should find the 3rd angle
75 + 50 + y = 180
125 + y = 180
y = 55
vertical angles are congruent, so the left angle on the right triangle will also be 55 degrees.
then you do the same thing to find x.
85 + 55 + x = 180
140 + x = 180
x = 40
