60% markup means 60 percent of 90 dollars added back into the price
45 is 60 percent of 90 dollars so you would add that to $90
Answer:
12 and -12
Step-by-step explanation:
Just square root 144
Y = 180 - 52 - 59 = 69 degrees . . . . . . . . (angles on a straight line are supplementary, i.e. add up to 180 degrees)
x = 180 - 69 - 63 = 48 degrees . . . . . . . . (sum of interior angles of a triangle is 180 degrees)
Therefore, m/_x = 48 degrees.
The formula you can use is
y - y1 = m(x - x1)
plug the y value you are given into y1 and the x value you are given into x1. m is for your slope value. after you plug in the known values, solve. your final answer should be in standard form which is
Ax + By = C
your answer should not contain any fractions and your Ax value cannot be a negative value, By and C can be negative though.
hope this helps :)
