Find the areas of the trapezoids. need in 10 minutes. will give 20 points! 6th-grade ! this is a test!

answer and step by step explanation:

identifying the area of trapezoid?

step 1: identify the length of both bases. the bases are parallel sides

step 2: add the lengths to the bases. for   8 cm and 13

step 3: identify the height of the trapezoid

step 4: multiply the sum of the lengths of the bases by the

step 5: divide the result by 2

answer:

the formula for area of a trapezoid is (base 1 * base 2) divided by 2, times the height

step-by-step explanation:

base 1 = top or bottom length

base 2 = the other base length

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
