Answer:

Triangle ABC is a right angled triangle.

Step-by-step explanation:

A triangle is called a right angled triangle if one of its interior angle is right angle.

The vertices of the triangle are A(0,2), B(2,-1) and C(-1,-3).

The slope formula is

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

m_{AB}=\frac{-1-2}{2-0}=-\frac{3}{2}

m_{BC}=\frac{-3+1}{-1-2}=\frac{2}{3}

The product of slopes of two perpendicular lines is -1.

m_{AB}\times m_{BC}=-\frac{3}{2}\times \frac{2}{3}=-1

Thus sides AB and BC are perpendicular to each other.

Since the measure of angle B is 90 degree, therefore triangle ABC is a right angled triangle.

Write the following decimal number in its equivalent fraction form. Show all work for full credit.

<span>Let x=0.8888... 

x=0.8888 Start with the given equation 

10x=8.8888 Multiply both sides by 10. The goal is to move the decimal point to the next repeating portion (which is just one spot to the right) 



 Now subtract the equation x=0.8888 from 10x=8.8888 to get 
10x-x=8.8888-0.8888 

9x=8 Combine like terms. Notice how the decimal portions cancel out. 

x=8/9 Divide both sides by 9 to isolate x 

So the answer is x=8/9 which means that 8/9=0.8888 (where the 8's repeat)</span>
