Answer:

acute isosceles

Step-by-step explanation:

Let A(2,5),B(8,3),C(2,1)

By distance formula,AB=BC=40^0.5

Hence, it is an isosceles triangle

Since AC=3, by cosine formula, AC=√(AB^2)+(BC^2)-2(AB)(BC)cosABC

angle ABC=36.8698765

Hence,it is an acute isosceles triangle

The following graph shows the number of customers who purchased something from a store in September and October. What is mislead
AleksandrR [38]

Answer:

C

Step-by-step explanation:

The graph is misleading because it exaggerates the difference.  September had 202 customers and October had 206.  That's a difference of 4 customers, which out of 202 isn't very much.  The graph doesn't start at 0, and that's why it looks exaggerated.

PLEASE ANSWER QUICKLY<br> (I will give first answer Brainliest)
Zina [86]

Answer:

The measure of Angle A is 45.5 degrees

Step-by-step explanation:

In order to find the measure of the angle A, add it to the measures of angle B and C. Since it is an isosceles triangle, we know that B and C have the same measure. Then we set this equal to 180.

A + B + C = 180

2x + 4 + 3x + 5 + 3x + 5 = 180

8x + 14 = 180

8x = 166

x = 20.75

Now we can find the measure of Angle A by putting the value of x in for x.

2x + 4 = A

2(20.75) + 4 = A

41.5 + 4 = A

45.5 = A

The area of a square can be found using the equation A = s², where A is the area and s is the measure of one side of the square.
Galina-37 [17]
Hi there!

Let's use the given formula of a square (A = s^2), to figure out what the equation would be. We are looking for one side, or s here. 

WORK:
81 = s^2
squareroot(81) = s

ANSWER:
The second option, root 81.

Hope this helps!! :)
