Answer:
y=50
Step-by-step explanation:
Answer:
D) 5
Step-by-step explanation:
This is the median of the trapezoid. It is the line segment that connects the midpoints of the non-parallel sides of the trapezoid.
The length of the median of a trapezoid is equal to 1/2 the sum of the bases; this makes ours
1/2(3.3+6.7) = 1/2(10) = 5
7x + 9y = - 27_________eq1
3x - y = 3__________eq2
Multiply eq 2 by 9 and then add the resulting eq with eq1.
eq2 x 9 gives us 27x - 9y = 27___________eq3
add eq3 with eq1 we get.
34x = 0.
where x=0/34
x=0.
substitute x into any of the above equations to get y.
substitute x into eq1. we get:
7(0) + 9y =-27
9y = -27
y= -27/9
y = -3.
angle 5 and angle 4 are exterior angles
