Answer:
A = 222 units^2
Step-by-step explanation:
To find the area of this trapezoid, first draw an imaginary horizontal line parallel to AD and connecting C with AB (Call this point E). Below this line we have the triangle CEB with hypotenuse 13 units and vertical side (21 - 16) units, or 5 units. Then the width of the entire figure shown can be obtainied using the Pythagorean Theorem:
(5 units)^2 + CE^2 = (13 units)^2, or 25 + CE^2 = 169. Solving this for CE, we get |CE| = 12.
The area of this trapezoid is
A = (average vertical length)(width), which here is:
(21 + 16) units
A = --------------------- * (12 units), which simplifies to:
2
A = (37/2 units)(12 units) = A = 37*6 units = A = 222 units^2
Answer:
3/4 of a book per month
Step-by-step explanation:
divide 3 by 4 because there are 4 months
The unit of measurement is not specified, so for the sake of this problem, we'll assume it's radians (If you need it in degrees, I'll be happy to edit).
Find the compliment of 0.25:
Complementary angles add up to 90 degrees. In radians, this would be π/2. If you're unsure how I got this, check degrees to radian conversions.
The compliment of 0.25 would be

(1/4=0.25)


(This is the simplified form in case you're homework needs it in this form)
That's the compliment. In decimal (rounded to the nearest hundredth), this would be 1.32 radians.
Find the supplement of 7π/8:
Supplementary angles add up to 180 degrees. In radians, this would be π.
The supplement would be the following:


Thus, the supplement is π/8 radians. If any of this struck you as confusing, comment and I'd be happy to clarify.
