ASAP MAJOR HELP NEEDED. I really need help. I am very confused on how to do this please help.
alexandr402 [8]

Because the 2 sides of the triangle are the same, they are both 21, the two bottom angles would also be the same.


The 3 inside angles of a triangle must equal 180 degrees.


The top angle is given as 38, so the remaining two angles must equal 180 - 38 = 142 degrees.


Since the 2 bottom angles would be the same, divide 142 by 2 to get x.

X = 142 / 2 = 71 degrees.

BlackZzzverrR [31]
Before we begin, let's cross out "the small wheel could have an 18 inch diameter". This is useless information and should be disregarded to avoid confusion. Lots of questions include extraneous information to make you second guess yourself, so it is important to be aware of what the question is asking you and what you need in order to answer it.

The formula for circumference is \pi x diameter. With this formula, we can substitute the value of the diameter, 52, into the equation.

Circumference = 3.14 x 52
Circumference = 163.28

Final Answer: the circumference of the big wheel is 163.28 inches
