Answer:
a1 = 4
a2= -2
a3 = -8
a4= -14
a5= -20
Step-by-step explanation:
a12= a1 + 11d
-62 = 4 + 11d
-62-4 = 11d
-66= 11d
d = 
= -6
a1 = 4
a2 = 4 - 6 = -2
a3 = 4 - (6×2) = -8
a4 = 4 - (6×3) = -14
a5 = 4 - (6×4) = -20
Answer:
Step-by-step explanation:
The triangle is isosceles, so the angles on either end of the parallel bases are congruent. Right away, that tells you y = 128°.
The angles at the side of a trapezoid are supplementary, so ...
x = 180° - 128°
x = 52°
