Answer:
17/2 or 8 and 1/2
Step-by-step explanation:
Answer:tan (7pi/8) = -4.4142
Explanation:The tangent half-angle formula is shown in the attached image
We have:
alpha = 7pi / 8
alpha/2 = 7pi / 16
Substitute in the formula with the alpha and alpha/2 as follows:tan (7pi/8) = [2tan(7pi / 16)] / [1 - tan(7pi / 16)tan(7pi / 16)]
tan (7pi/8) = -4.4142
Hope this helps :)

Answer:
Trapezoid
Step-by-step explanation:
We have been given that Marcus drew a quadrilateral with only 1 pair of parallel sides. We are asked to determine the quadrilateral that Marcus drew.
We know that a parallelogram has two pair of parallel sides.
We also know that rhombus is a parallelogram whose 4 sides are equal is measure and rectangle is a parallelogram with opposite sides equal.
Since parallelogram, rhombus and rectangle has two pair of parallel sides, therefore, Marcus didn't draw any of these.
We know that trapezoid has only one pair of parallel sides, therefore, Marcus drew a trapezoid.
