Answer:
135 degrees.
Step-by-step explanation:
Tan theta = √/2 /2 / -√/2 /2 = -1
Arctan 1 = 45 degrees.
As the x coordinate is negative and the y coordinate is positive:
Theta will be in the 2nd quadrant.
So its 180 - 45
= 135 degrees.
so since Mrs Jackson used 2/15 of 7/8, the amount she used is simply their product.
