Help me out:( Don’t forget to explain pls :(

When you find the volume of a triangle, remember to do this:

Step-by-step explanation:

Multiply the base times the height, then divide by two.

The mistake is in the second triangle and is noticeable at first because the length of the leg is longer than the length of the hypotenuse.

Since this is a 30 60 90 triangle, you can use the properties that apply to them. I'm assuming that the leg with the length of 62ft is the given side. Using the rules, we know that x/2 is 62 (since the properties of a 30 60 90 triangle state that the shortest side is x/2). In order to find the hypotenuse (which is x), we can multiply both sides of the equation x/2 = 62 to get x = 124. To find the second leg, we need to use sqrt(3)*x/2, which when you plug in 124, gives 107.39. Andrea just switched the lengths of the second leg and the hypotenuse on accident.

the answer is 31.27mph
