Answer: 70
Step-by-step explanation:
Because opposite sides of a parallelogram are equal, AB=CD. So,
2x-10=x+30
x=40
Therefore, AB=2(40)-10=70
6 3/7 multiplied by 21 is 135. Your answer is C. 135 <span />
All triangles have 180o in them when the 3 angles making them up are added together.
Givens
F = 90
E = 29
D = ???
Equation
<D + <E + <F = 180
Substitute and solve
<D + 90 + 29 = 180
<D + 119 = 180
<D = 180 - 119
<D = 61
Answer:
y = -6x - 42
Step-by-step explanation:
First solve for y in x = 6 + 6y.
6y + 6 = x
6y = x - 6
6/6y = x/6 - 6/6
y = 1/6x - 1 the slope is 1/6.
Perpendicular lines slopes are negative reciprocals of each other.
So the new equation will have the slope of -6 ( the negative reciprocal of 1/6)
Next solve for "b" by using y = mx + b and the new slope of -6 and the point (-8,6)
y = mx + b
6 = -6(-8) + b
6 = 48 + b
-42 = b
The equation of the line is y = -6x - 42
