Given:
In ΔWXY, x = 680 inches, w = 900 inches and ∠W=157°.
To find:
The all possible values of ∠X, to the nearest degree.
Solution:
Law of Sines:
For ΔWXY,
Now,
Therefore, the value of ∠X is 17 degrees.
Answer:
Option A ( -3/2 , )
Step-by-step explanation:
- According to Question, The Spinner Rotate 600* Thus after Completing 360* it Comes Exactly Where It Started . Now again rotate It 180* .
- Now We Are on ( -X axis ) & Completed 360*+180*=540* Rotation
- Now After Rotate It 60* More we come in Third Quadrant & Here In Third Quadrant Only Tangent & Cotangent Is Positive .(Sine & Cosine is Negative)
(For Diagram, Please Find in attachment)
Now In Triangle OAB
- Cos60* = OA / OB
1/2 = -X / 3 Thus X= -3/2
- Sin60* = AB / OB
/2 = -Y / 3 Thus Y = -
* 3 /2
