Answer:

1a. 8

1b. AB & BC

1c. AC

2. \sqrt{52} miles

3. NO

Step-by-step explanation:

1a. AC is your hypotenuse which is C² and BC is B², so we plug it in the equation.

A²+6²=10²

A²+36=100

A²=64

A=\sqrt{64}

A=8

1b. Legs are the two shorter sides, AB & BC, which are 6 & 8 respectively.

1c. The hypotenuse is the longest side AC

2. Make lines that make the graph for a triangle with a line. My graph is linked below. Then counts the points, AC=6, BC=4, then use the pythagorean therom.

6²+4²=X²

36+16=52

\sqrt{52}=X

3. 15²+17²=19²

514=361

not possible

so it is not a right triangle

What's 80÷7 I need this answer fast thank you it's for 65 points
klemol [59]
In order to solve this, we must find out how many times 7 goes into 80. We can do this by either subtracting individual 7s from 80, or by adding 7s together until we cannot add another without going past 80.

For this answer, I will use the addition method.

7 + 7 = 14

14 + 7 = 21

21 + 7 = 28

28 + 7 = 35

35 + 7 = 42

42 + 7 = 49

49 + 7 = 56

56 + 7 = 63

63 + 7 = 70

70 + 7 = 77

From 77, we cannot add another 7 to it without going over 80, since 77 + 7 = 84.

So, let's count the sevens that we have added up so far, and when we do, we can see that there are 11 of them, adding up to 77.
So 7 goes into 80 11 times. Now, let's find the remainder...

To find the remainder, you just need to subtract the final added number from the number you are dividing from.

80 - 77 = 3

80 / 7 = 11, remainder 3
Hope that helped! =)

To find the area of the full shape, we can find the areas of individual smaller shapes and add them together. Lets break this up into a rectangle and a triangle.


The rectangle is easy to calculate as we already have its measurements. The area of a rectangle is h*w=A.

25*36=A

900=A


Next the triangle, and we need to do some logic work with the measurements to find the necessary measurements to take the area.


We know the base of the triangle is some part of 36 feet. We also know from the image that the part of the 36 that is not part of the base of the triangle is 12. Therefore, the base of the triangle is 36 - 12 = 24.


Now we need the height of the triangle. We know the height of the triangle is some part of 39, and the part that is not part of the triangle is 25. Therefore, the height of the triangle is 39 - 25 = 14.


We now have the height and base of the triangle and can find its area. The area of a triangle is 0.5wh=A.

0.5(24)(14)=A

168=A


Finally, we just need to add the two results together to find the total area.

168 + 900 = A

1068 = A


The total area of the shape is 1068.
