Answer:
See below.
Step-by-step explanation:
Triangle ABC will be right-angled if 2 of its sides are perpendicular to each other. When sides are perpendicular the product of their slopes = -1.
Slope of side AB = (-3-2)/(2-5) = -5/-3 = 5/3
Slope of side BC = (3- -3) / -8-2) = 6/-10 = -3/5
The product of the slopes = 5/3 * -3/5 = -15/15 = -1.
So AB is perpendicular to BC and triangle ABC is right-angled .
What is the question to this explanation?
Answer:
A) R
B) B
C) E
I only know these answers :)
Slope =4/7 because you subtract 4x to the other side then divide by -7 qnd the number next to x is the slope in the slope intercept form
√(154)
√(77 × 2)
√(77)√(2)
√(11 × 7)√(2)
√(11)√(7)√(2)
The square route of 154 is irrational.
