Answer:
x=34
Step-by-step explanation:
1. formula for Pythagorean Theorem for right trangles is <u>a^2+b^2=c^2</u>
2. a=30 and b=16, so (30)^2+(16)^2=c^2
3. (30)^2=900 and (16)^2=256
4. 900+256=1156
5. 1156=c^2
6. ![\sqrt{1156} =\sqrt{c^2}](https://tex.z-dn.net/?f=%5Csqrt%7B1156%7D%20%3D%5Csqrt%7Bc%5E2%7D)
7. the square root of 1156 is 34, so c=34
8. The missing side of the triangle, labeled as "x<em>"</em> is 34
Yes I can. What every u need to ask I can help.
Answer:
Yes.
Step-by-step explanation:
A quadrilateral just has to have 4 sides. They do not need to be equal sides. This means that you can have any angles you want, as long as they add to 360.
Answer: 455 mph
Step-by-step explanation:
if train one is traveling one way at 60mph, then you have to multiply that by 3.5 to see how far it traveled in that amount of time.
60 x 3.5 = 210
then, you have to multiply 3.5 by 70mph, to see how far the second train has traveled in that amount of time
70 x 3.5 = 245
finally, since both trains are moving in opposite directions, you have to add up the distances together to get the final difference
210 + 245 = 455
