12 x 10 =120
120= to 12 tens
So always know that midpoint is y2+y1/2 and x2+x1/2
So since the points are A(-3, -2) B(7,3)
We'll make A 1
And B 2
So it becomes (3+(-2))/2 (7+(-3))/2
So C is your answer :)
Since angle C is not 90 degrees, it's one of the acute angles
in the right triangle.
(The side adjacent to angle C ) divided by (hypotenuse)
is the cosine of angle C .
(adjacent) / (10 inches) = cos(40 degrees)
Multiply each side by (10 inches):
Adjacent side = (10 inches) x cos(40) =
(10 inches) x 0.766 =
7.66 inches (rounded)
