84-14=70/2=35+14=49+35=84
The numbers are 49 and 35
Answer:
The volume is:
cubic units
Step-by-step explanation:
Volume of a solid:
The volume of a solid, given by the function f(x), over an interval between a and b, is given by:

y = x, y =1, x = 0
This means that the upper function is y = 1, and the lower function is y = x. So

The lower limit of integration is x = 0.
The upper limit is y = x when y = 1, so x = 1.
Then






Answer: C
Step-by-step explanation:
We know that A and D will not be the correct answers. For A, it's only one 90 angles, but the questions said that has two angles. For D, it's two angles : 90 and 12, but in the question, 12 is the length, not the angle.
The correct answer is C.
