Answer:
b=4
Step-by-step explanation:
Let us draw a triangle ABC, with A = 63°, C = 49°, and c = 3.
In the triangle ABC,
A +B +C = 180°
63°+B+49°= 180°
B = 180°-63°-49°
B = 68°
Use Sine law to find b
In the nearest whole number b = 4

Answer:
There are 6 boxes
Step-by-step explanation:
We know there are 45 frames and 3 broken ones, so there are 48 frames in total.
We know there are 8 boxes that have the frames.
let x equal the amount of picture frames in a box
8x=48
8x/8 = 48/8
x=6
