8.76 * 10^9 * 6.52 * 10^-3

= 57.1152 * 10^6

57.1152 * 10^6 / 13.27 * 10^5

= 4.30408 * 10^1 which can be written as 43.0408 ( correct to 4 dp's)

<u>Trigonometry</u>

  • [Right Triangles Only] SOHCAHTOA  
  • [Right Triangles Only] sinθ = opposite over hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

Angle θ = ∠R

Opposite Leg of ∠R = 10√3

Hypotenuse = 20

<u>Step 2: Solve</u>

  1. Substitute in variables [sine]:                                                                         \displaystyle sin(R^\circ) = \frac{10\sqrt{3}}{20}
  2. [Equality Property] Trig inverse:                                                                    \displaystyle R^\circ = sin^{-1}(\frac{10\sqrt{3}}{20})
  3. Evaluate trig:                                                                                                   \displaystyle R = 60^\circ

In the coordinate plane, a circle has center (2, -3) and passes through the point (5, 0).
ICE Princess25 [194]

Answer:

C) 18

Step-by-step explanation:

In order to get the answer to this word problem you have to mentally image in your head looking at a coordinate graph. You see the point (2, -3) which is on the x or y axis. You see the point (5, 0) which is also on the x or y axis. When those two points or coordinates cross, they get the number 18.
