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 righ

levacccp [35]

Answer:

Yes, the right angle is angle C.

Step-by-step explanation:

The given triangle has vertices at A(–2, 3), B(–3, –6), and C(2, –1).

Recall the slope formula;

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of the line going through AC is

$m_{AC}=\frac{-1-3}{2--2}=-1$

The slope of the line going through BC s

$m_{AC}=\frac{-1--6}{2--3}=1$

The product of the slopes of AC and BC is $-1\times1=-1$

This means line AC is perpendicular to BC at C.

Hence the triangle ABC is right angled at C.

Mila [183]

Answer:

(-3/5, 29/5)

Step-by-step explanation:

Given the simultaneous equation;

-3x+4y=25...... 1

y= -3x+4 ..... 2

We are to confirm if (-3, 4) is the solution to the equations;

Substitute equation 2 into 1;

From 1;

-3x+4y=25

-3x + 4(-3x+4) = 25

-3x -12x + 16 = 25

-15x = 25 - 16

-15x = 9

x = -9/15

x = -3/5

Substitute x = -3/5 into equation 2 to get y;

From 2;

y= -3x+4

y = -3(-3/5)+4

y = 9/5 + 4

Find the LCM

y = (9+20)/5

y = 29/5

Hence the solution to the system of equation is (-3/5, 29/5) hereby falsifying Julie's solution.
