Step-by-step explanation:To find inverse for this problem interchange the variables and solve for y
The reflection will be on the other side of the y-axis.
Its coordinates will be (3, 7).
Answer
63.2 degrees
Step-by-step explanation:
Using law of cosines: 19^2=8^2+14^2-2(8)(14) cos (x)
361=64+196-224 cos(x)
361=260-224cos(x)
101=224cos(x)
divide both sides by 224, which gets you (rounded to 4th decimal place) 0.4509. do inverse cos which gets you 63.2
