- the type of pair is vertical angle.
- to find x:
-- vertical angles are equal.
4x + 10 = 5x - 1
10 = x - 1
x = 11
Answer:
$150
Step-by-step explanation:
it is $25 income tax every $100 earned so 25 x 6 = 150
Answer:
The two integers are 20 and 22.
Step-by-step explanation:
Let x be the first integer.

Let the speed of plane in still air be x and that wind be y
therefore:
x+y=490
x-y=390
next we solve for the values of x and y, first we add the above equations. This will give us:
2x=880
x=880/2
x=440 miles per hour.
substituting the value of x in one of the equations and solving for y we get:
440+y=490
y=490-440
y=50 miles per hour
Angle A = 45, it’s opposite angle is 45
It’s adjacent is 135 degrees for total of 180 on each parallel line
