Answer:
2nd option
Step-by-step explanation:
the quadrilateral has 1 pair of parallel sides and is therefore a trapezoid.
• each lower base angle is supplementary to the upper base angle on the same side, that is
∠ 1 + ∠ 2 = 180° , so
x + x + 50 = 180
2x + 50 = 180 ( subtract 50 from both sides )
2x = 130 ( divide both sides by 2 )
x = 65
then
∠ 1 = x = 65°
∠ 2 = x + 50 = 65 + 50 = 115°
Answer:
-4(a + b = 6)
Step-by-step explanation:
When you multiply equation P by -4, you obtain -4a - 4b = -24. You can then add this equation to equation Q to eliminate the a term.

Answer:
r = 31.85 in or 100/π
Step-by-step explanation:
area = πd
200 = 3.14d
d = 63.69
r = 1/2d
r = 31.85 in
