If \triangle ABC△ABC is equilateral, solve for x. <br><br><br><br><br> x=
Gwar [14]

Answer:

x = 13

Step-by-step explanation:

The tirangle ABC is given as equilateral. Every angle is therefore =. Not only that, each angle is 60 degrees.

If you need proof of that, remember that x + x + x  = 180. Every triangle has 180 degrees.

if 3x = 180 then 1 x is 60

8x - 44 = 60       Add 44 to both sides.

8x = 60 + 44

8x = 104             Divide by 8

x = 104/8

x = 13

What is the volume of a rectangular prism with a length of 7m, a hight of 9m and a width of 11m
vazorg [7]
Hello!

To find the Volume of the Rectangular Prism, you'll need to multiply all of the measurements together. So you'll need to multiply 7, 9, and 11 together.

V=7*9*11

First, you'll need to multiply 7 and 9. Once you've multiplied 9 and 7 together, you should have 63. Now you should multiply 63 and 11 together. Once you've multiplied 63 and 11 together, you should have a Volume of 693

You should have a Volume of 693m³

I hope this helps!

David has $9.39 but needs $15.00 to make a purchase. How much more does he need?
elena-14-01-66 [18.8K]

Answer:

$5.61

Step-by-step explanation:

Since David only has $9.39 but he needs $15.00 for his purchase. So, you would subtract the $9.39 from the $15.00 to see how much more money David needs to make this purchase.

15.00 - 9.39

When you carry out this problem, it equals $5.61.

Therefore, David needs $5.61 to be able to complete his purchase
