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.

Find the solution of this system of equations. Separate the x- and y-values with a comma.

vivado [14]

X = -6 + y...so we sub in -6 + y for x in the other equation

x - 3y = 28
-6 + y - 3y = 28
-2y - 6 = 28
-2y = 28 + 6
-2y = 34
y = -34/2
y = - 17

x = -6 + y
x = -6 - 17
x = - 23

solution is (-23,-17)

Norma had 3/8 left over from her party .She ate 3/4 of the leftover cake at lunch how much of the cake did Norma have at lunch

sergejj [24]

Answer:

Norma ate $\frac{9}{32}$ of the leftover cake at her lunch.

Step-by-step explanation:

Norma had a leftover cake from her party = $\frac{3}{8}$

She ate $\frac{3}{4}$ th of the leftover cake at the lunch.

Therefore, amount of cake she had at lunch = $\frac{3}{8}\times \frac{3}{4}$

= $\frac{9}{32}$ of the leftover cake

Norma ate $\frac{9}{32}$ of the leftover cake at her lunch.
