Vaselesa [24]

Answer:

  -3 comes from combining 1 and -4

Step-by-step explanation:

The -3 under the radical is the result of combining the terms

  16 -4(16) = 16(1 -4) = 16(-3) = -3(16)

16 is factored out. It is done this way because 16 is a perfect square factor, so wants to maintain that identity while you figure out the rest of the radical.

  =\dfrac{-4\pm\sqrt{16-4(16)}}{2}=\dfrac{-4\pm\sqrt{16(1-4)}}{2}=\dfrac{-4\pm\sqrt{-3(16)}}{2}\\\\=\dfrac{-4\pm\sqrt{-3(4^2)}}{2}=\dfrac{-4\pm 4\sqrt{-3}}{2}=-2\pm2\sqrt{-3}=-2\pm2i\sqrt{3}

Find the measure of each angle indicated. Round to the nearest tenth.
Sladkaya [172]

Answer:

D

Step-by-step explanation:

So we want to find<em> θ. </em>We are already given the hypotenuse and the side length opposite to <em>θ. </em>Therefore, we can use the trig function sine to find <em>θ. </em>

Recall that:

\sin(\theta)=opp/hyp

Plug in 10.2 for the opposite side and 15 for the hypotenuse:

\sin(\theta)=10.2/15

Solve for <em>θ. </em>Use a calculator:

\theta=\sin^{-1}(10.2/15)\\\theta\approx42.8436\textdegree

The answer is D.
