32 + 5 × 2 − 8
32+10-8
42-8= 34
The answer should be 34 but I don't see it up there
:/
Answer:
Because θ lies in quadrant II, 2θ must lie in quadrant IV. This means the tangent of 2θ is negative.
The adjacent side to θ is 7 because √(25²-24²)=7, so tanθ=7/24.
The double angle formula for tangent is tan 2θ = (2 tan θ) / (1 − tan² θ).
Substituting the value for tanθ in and keeping in mind that this is in quadrant IV, we get tan 2θ = -(2(7/24)/(1-(7/24)²)).
Simplified, this becomes tan 2θ = -336/527.
Therefore, the answer is C. -336/527.
5 - 6 = -1
2 + 7 = 9
-1 × 9 = -9
-9 would be the simplified answer.
Hope this helps!
I'm gonna say A. It makes the most sense to me.
Use the pythagorean theorm
16^2 + 12^2 = c^2
256 + 144 = c^2
400 = c^2
c = 20 feet or a
