When the base of the ladder is 10 ft away from the base of a building, the top of the ladder touches the building 18 ft above the ground about how long is the ladder

32

Step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
