Lisa is asked to draw a triangle that has one interior angle with a measure of 60 degree. The other 2 angles have measures of x and y. Which of these could be the values of x and y? Choose all that are correct. A. X=45, y=45
B. X=100, y=20
C. X=40, y=80
D. X=60, y=69
E. X=50, y=90

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
