Answer:
B
Step-by-step explanation:
In an isosceles trapezoid any lower base angle is supplementary to any upper base angle, thus
6x + 2x + 4 = 180, that is
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22 → B
Answer: 3x + 2y - 4z= -7= <em><u>-5/8</u></em>
<em><u></u></em>
x - 4y + 3z = 10= 11
2x + 2y - 3z= -5= -2
