Step-by-step explanation:
5kgthe following ratio in the simplest form
(secx + tanx)^2
<span>secxsecx + secxtanx + secxtanx + tanxtanx
</span>secxsecx + 2secxtanx + tanxtanx
tanxtanx + 1 + 2secxtanx + tanxtanx
2tanxtanx + 1 + 2secxtanx <span>
The expression (secx + tanx)2 is the same as </span>1 + 2tan2x + 2secx tanx. The answer is letter D.
Beacuse you are adding UVW to WVX, it would be: B. Angle Addition Postulate
