Answer:
80
Step-by-step explanation:
area of a trapezoid: (base1+base2)/2 * height
(3+17)/2 *8 = 10*8 = 80
Answer:
c) -6
Step-by-step explanation:
50 + 90 + (x+46) = 180 (angle sum property)
186 + x = 180
x = 180 - 186 = -6
I hope im right!!
A (b-c) = d
b-c = d/a
-c = (d/a) - b
-c = (d-ab) /a
c = (ab-d)/a
Answer:
Cube both sides tham solve the resulting quadratic
