Two sides of an isosceles triangle measure 3 inches and 13 inches respectively. Find the length of the third side. Explain your reasoning.

Answers

Answer 1

Answer: Because the triangle is isosceles, two sides have the same length.

So, the triangle may have sides 3, 3, 13 OR 3, 13, 13

The triangle inequality theorem states that one side of a triangle is less than the sum of the other two.

3, 3, 13 cannot be the sides of any triangle because 13 is not less than 3 + 3 which is 6.

3, 13, 13 are the lengths of the triangle with 13 being the length of the third side.

Answer 2

Answer: An isosceles triangle is a triangle that has two sides of equal length. If the lengths of two sides of this isosceles triangle are 3 inches and 13 inches, then the third side would be a length of 13 inches.
This can be reasoned in that a base of 13 inches is too wide for two sides of 3 inches to meet and create a triangle, but a base of 3 inches would make a base small enough for two sides of 13 inches to meet and form an isosceles triangle.

How to turn into mixed number

Answers

you can divide 5 by 9 and get 1 4/5
how you get that is when dividing the number on top is always the whole number,
the number that is left is the numerator
the number on the side is the denominator
hope this helps! and hope its not confusing:)

This as a mixed number is 1 4/5 because when we do 9/1 x 1/5 it gets us 9/5. We have to change 9/5 as a mixed by seeing how much times the numerator which here is 1, and how much nummbers are left over so 4 and we leave the denominator as 5, so we get 1 4/5

Which of the following angle measurements might you find in a right triangle?45°, 45°, 90°
50°, 50°, 90°
60°, 60°, 60°
90°, 90°, 90°

Answers

Answer:

The first one! 45,45,90

Step-by-step explanation:

The sum of angle is 180, so Only

45+45+90=180

50+50+90=190 it is greater than 180 ist not Ok

60+60+90=210 it is not ok

90+90+90=270 is not ok

So elimination sounds fun but we will have to do manipulation:

Multiply top equation by 2 and bottom equation by 3. This will cause the second term in both by 6y which means we would be setup for elimination.

8x+6y=34

9x+6y=39

--------------------now subtract the equations

-x+0=-5

So x=5

Now plug it into either question (no matter which-pick and choose)

I will go with the second original 3x+2y=13

So if x=5 we have 15+2y=13

Subtract 15 on both sides: 2y=-2

Now divide both sides by 2: y=-1

During the day, the manager of the meat department sold 15.4 pounds of hamburger to one customer and 13.22 pounds to another customer. When the store opened that morning, he had 35.75 pounds of hamburger to sell. How much hamburger does the manager have left to sell? lb

Answers

The total amount of hamburger that the manager of the store in the morning = 35.75 pounds
Quantity of hamburger sold to one customer during the day = 15.4 pounds
Quantity of hamburger sold to another customer during the day = 13.22 pounds
Total quantity of hamburger sold
by the manager during the day = (15.4 + 13.22) pounds
= 28.62 pounds
Then
The quantity of hamburger left in the store to sell = (35.75 - 28.62) pounds
= 7.13 pounds
So 7.13 pounds of hamburger is still left to be sold.
