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.

The question is an illustration of a division model.

The boxes will be completed with: 1650, 231, 50 and 7

The expression is represented as:

$\mathbf{1881 \div 33}$

Express 1881 as 1650 + 231.

$\mathbf{1881 \div 33 = (1650 + 231) \div 33}$

Split

$\mathbf{1881 \div 33 = 1650 \div 33 + 231 \div 33}$

Evaluate each division

$\mathbf{1881 \div 33 = 50 + 7}$

$\mathbf{1881 \div 33 = 57}$

The above illustration means that, the boxes will be completed with the following numbers
