Answer:
D) 5
Step-by-step explanation:
This is the median of the trapezoid. It is the line segment that connects the midpoints of the non-parallel sides of the trapezoid.
The length of the median of a trapezoid is equal to 1/2 the sum of the bases; this makes ours
1/2(3.3+6.7) = 1/2(10) = 5
First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2
Now, this is the answer for angles between 0 and 2pi
but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:
x = pi/2 + n*pi
here n is any integer.
Answer:
-31
Step-by-step explanation:
-34 - -17 is actually -34 + 17, so you get -17. -17 - 14 = -31
