HELPPPPPPPP<br><br> In WXY, y=690 cm, w=440 cm and angle X=163°. Find angle W to the nearest degree
Ede4ka [16]

Answer:

The angle W is approximately 7°.

Step-by-step explanation:

Since angle X is adjacent to sides y and w and opposite to side x, we calculate the length of side x by Law of the Cosine:

x = \sqrt{y^2+w^2-2\cdot y\cdot w \cdot \cos X} (1)

Where:

y, z - Side lengths, in centimeters.

W - Angle, in sexagesimal degrees.

If we know that y = 690\,cm, w = 440\,cm and X = 163^{\circ}, then the length of the side x is:

x = \sqrt{y^2+w^2-2\cdot y\cdot w \cdot \cos X}

x\approx 1118.199\,cm

By Geometry we know that sum of internal angles in a triangle equals 180°. If X is an obtuse, then Y and W are both acute angles. By Law of the Sine we find angle W:

\frac{x}{\sin X}= \frac{w}{\sin W} (2)

\sin W = \left(\frac{w}{x} \right)\cdot \sin X

W = \sin^{-1}\left[\left(\frac{w}{x} \right)\cdot \sin X\right]

If we know that X = 163^{\circ}, w = 440\,cm and x\approx 1118.199\,cm, then the angle W is:

W = \sin^{-1}\left[\left(\frac{w}{x} \right)\cdot \sin X\right]

W \approx 6.606^{\circ}

Hence, the angle W is approximately 7°.

Halp meh ;w; Also hope everyones have a good day
Alex17521 [72]

10/3 goes where 3 and 1/3 is.

This is because 10/3 as a mixed number is 3 and 1/3.

17/3 is where 5 and 2/3 is. Do the same thing as before.

Hope this helps!
