△ABC  right angle C, leg BC > leg AC.  So angle A > angle B.

a=BC, b=AC, c=AB

a > b

sin A= cos B = a/c

sin B = cos A = b/c

a = c sin A = c cos B

b = c sin B = c cos A

a > b

c sin A > c sin B

sin A > sin B

c cos B > c cos A

cos B > cos A

Answer:  B, E

Crank

Substitute y=\ln(2x+1) and dy=\frac2{2x+1}\,dx, so that

\displaystyle \int \frac2{(2x+1) \ln(2x+1)} \, dx = \int \frac{dy}y = \ln|y| + C = \boxed{\ln|\ln(2x+1)| + C}

What type of Symmetry
nikklg [1K]

Answer:

Line Symmetry, Horizontal and Vertical Lines, 90 and 180 degrees

Step-by-step explanation:

It is line symmetry because you can fold the H, and it would overlap perfectly.

Horizontal and vertical lines because if you were to place a line in the middle both horizontally and vertically it would overlap.

90 and 180 degrees because the H would still have have symmetry if you flipped it on its side or upside down.
