The equation for surface area is:

. To get r, you must use Pythagorean theorem. r is found to be 45. This means after you plug it in, you get about
13571.68
Answer:
32 degrees.
Step-by-step explanation:
So every triangle =180 degrees.
Firstly, 14 + 45 = 59
Secondly, 180 - 59 = 121
so angle AEB = 121 degrees.
Using vertical angles theorum, angles AEB and CED are equal to each other
so CED = 121 degrees.
121 + 27 = 148
then 180 - 148 = 32
Angle D = 32 degrees
(might want to fact check this I am pretty tired
Answer:
x^2-5x + 6
Step-by-step explanation:
Here, we want to expand the given expressions
To do this, we multiply each term in the first bracket with each term in the second
We then proceed to collect like terms
We have this as;
x(x-3) - 2(x-3)
= x^2 - 3x -2x + 6
= x^2 -5x + 6
Answer:
5/21
Step-by-step explanation:
1/7 + 2/21 = ?
lcd of 7 and 21 is 21 so;
( 2/21 x 1/1) + 1/7 x 3/3) = 5/21
