The way is see the problem causes the answer to be 27x<span />
answer
z = 100
opposite angles
when inscribed in a circle, the opposite angles of a quadrilateral add up to 180
so z + 80 = 180 and y + 120 = 180
solve for z
z + 80 = 180
z = 180 - 80
z = 100
Answer: 1.5miles/hour
Step-by-step explanation:
Answer:
216
Step-by-step explanation:
There 2 angles are corresponding angles, in which the angle measurements would have the same degree.
Set the two angles equal to each other, and solve for x.
7x - 1 = 8x - 14
Isolate the x. Subtract 8x from both sides, and add 1 to both sides
7x (-8x) - 1 (+1) = -14 (+1)
7x - 8x = -14 + 1
-x = -13
Isolate the x. Divide -1 from both sides
(-x)/-1 = (-13)/-1
x = -13/-1
x = 13
13 is your answer for x.
