Answer:
approximately 12.04 units
Step-by-step explanation:
We'll use the Pythagorean Theorem to solve this problem.
There are two points here. The horizontal distance between them is 8 units and the vertical distance is 9.
According to the Pythagorean Theorem (or the Distance Formula), the distance between the two points is
d = √(8^2 + 9^2) = √(64 + 81) = √145 units, or approximately 12.04 units.
Answer:
x=15
Step-by-step explanation:
These angles are corresponding angles and with parallel lines corresponding angles are equal
9x+19 = 10x+4
Subtract 9x from each side
9x+19 -9x = 10x+4-9x
19 = x+4
Subtract 9 from each side
19-4 =x
15=x
