Triangle abc has vertices at a(–2, 3), b(–3, –6), and c(2, –1). is triangle abc a right triangle? if so, which angle is the right angle?

a.) no, the triangle has no right angles.
b.) yes, the right angle is angle a.
c.) yes, the right angle is angle b.
d.) yes, the right angle is angle c.

D

Step-by-step explanation:

the slope of AC is -1, and the slope of BC is 1. Perpendicular slopes are opposite and negative, meaning you take the reciprocal of the slope and multiply it by -1 to get the perpendicular slope. 1 has a reciprocal of 1, and multiply by -1 gives -1.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

360/29
