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°

100:20
Step-by-step explanation:
Hi I am sorry if i give you the wrong answer but I think it's three games and 2 movies because 6 times 3 = 18 then 4 times 2 = 8 and 18 + 8 = 26 :)
Step 1; multiple equation 2 by -2: 14x+8y=-18
step2: subtract this new equation from equation 1 to eliminate x:
2y-8y=18-(-18)
-6y=36
y=-6
step 3: substitute y=6 in equation 2: -7x-4*(-6)=9, -7x=-15, x=15/7
