Answer: 89.1

Step-by-step explanation: Firstly, for the square, you would multiply 8 by 8 which would result in 64. That is your first addend. Next, to find the area of the semicircle, you find the area of a whole circle, then divide by two. In this case, the area formula would be (pi)r^2. So, the radius would be 4, and in he formula that would end up with the answer being 50.24. Then, you divide by two. 25.1 (rounded to tenths) + 64 = 89.1.

Hope this helped!!

Rewrite 2tan112.5/1-tan^2(112.5) using a double-angle identity.

Paraphin [41]

The following identity can be used:
$tan\ 2\theta=\frac{2\ tan\theta}{1-tan^{2}\theta}$
$\frac{2\ tan(112.5)}{1-tan^{2}(112.5)}=tan(2\times112.5)=tan(225)$
