Answer:
it is a 60 30 90 triangle so basically 2y is = x
21² + y² = x²
441 + y² = x²
y = x/2 (2y = x)
441 + x²/4 = x²
4x² = 1764 + x²
3x² = 1764
x = exact is 24.248711306 simplied square root would just be 14√3
2y = 14√3
y = 7√3
exact wouldd be 12.124355653
Answer:
Because the 
The integral converges to 
Step-by-step explanation:
For this case we want to find the following integral:
And we can solve the integral on this way:
And if we evaluate the integral using the fundamental theorem of calculus we got:
Because the
The integral converges to
Answer:
it is heptagon and sum of interior angles of heptagon is 900 °
123°+131°+ 125°+124°+x 129°+132° = 900°
764° +x = 900 °
x = 900°-764°
x = 136°
Answer:
well when you are dividing you can multiply the answer and the second number to get the first number. And when you multiply you can divide the answer to any of the number to get the other number. Hope this helped!
