If there aren’t any degrees and it doesn’t state that the triangle is equilateral then you cannot solve this equation without more information
So if you do 8x14=112 is the area. So 112 divided by 40= 2.8. He will need 2.8 pints of paint.
C.Quadrilateral is the answer for the following because rhombus, trapezoid, isosceles trapezoid have parallel sides.
The slope of the given line = 1 so the slope of the line perpendicular to it will be -(1/1) = -1.
It also passes through point (1, -1) so we use the point slope equation
y - y1 = m(x - x1)
y - -1) = -1(x - 1)
y + 1 = -x + 1
y = - x <--------- that's the answer
