(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.
Let's prove triangle DEF:
10/7=1.428571429 different to 1.5=9/6, then triangle DEF is not similar to triangle ABC
Let's prove triangle GHI:
3.5/7=0.5=3/6, then triangle GHI is similar to triangle ABC
Answer: Option B. GHI
Hello!
A straight line measures to 180°
The angle that measures 134 and x make a straight line
180 = 134 + x
Subtract 134 from both sides
46 = x
The answer is 46°
Hope this helps!
