Answer:
-70
Step-by-step explanation:
If a number is right by a parathesis () then you multiply the number inside the parathesis by the number next to them.
7 mm wide
To solve this, you can use the Pythagorean theorem.
A triangle's sides is length squared + length squared = hypotenuse squared. We know the hypotenuse and one side of the triangle. So, we can follow the equation 24 squared + x squared = 25 squared
To solve this, find the value of 24 squared and 25 squared. 24 squared = 576, and 25 squared = 625, so your equation becomes 576 + x squared = 625
Next, you subtract your known values. 576 + x squared – 576 = 625 – 576 = 49, so x squared = 49
For the last step, find the square root (√) of 49, which is 7. So x = 7 mm
And you can check: 24 squared + 7 squared = 25 squared
Answer:
222
Step-by-step explanation:
To start with we have to write down what we know. pi=3.14, r=9, arc length is 1. x is the angle we are trying to find. Saying that the radius is 9
There is an equation that states that the arc length is equal to x/360 (the fraction of the circle) multiplied by the circumference or 2 times pi times the radius.

where * means multiply.

Simplify

Take the 28.26 over to the other side of the equation, where it then it divides the 1.

This becomes:

Then the 360 is brought over to the other side and multiplies the 0.035:

And finally simplify the whole equation and we get our answer.
