No. Just because the angles are all less than 90 degrees, that doesn't tell us anything about the sides. The sides are all congruent ONLY if all 3 angles are 60 degrees each. If the angles all have different sizes, then so do the sides.
18)k=37
20)q=-17
22)c=-26
24)y=-76
26)r=20
28)n=-15
30)k=25.8
32)n=3.64
34)y=1/8
36)s=-17
38)x=67
40)x=-55
Answer
the answer would be 2x^2
really hope it helps it kinda confused me for a second lol
Actually you should look it up there are so answers that can help you solve them<span />
SinØ(TanØ+2)=3cosØ -----[pulling like terms out]
for the following steps The easiest 4 me is that I just plug in values between 0° and 180° for Ø and see which will help me to get equal numbers on both sides.
So, for instance if you use Ø=90°, you'll get the following, Sin90(Tan90+2)=3cos90
========> 1(1+2)=3(1) ==> 3=3
so 90° is one of the solutions ur looking for.
hope this was helpful
