Sin=12(3)=76(tk87) hope this helped you have a nice day
Answer:
Step-by-step explanation:
To find the area of the triangle, you use the formula A=bh/2. This gives you the area of 49in^2 for the triangle, eliminating choices C and D. The area of the entire square is 14^2, or 196in^2, which gives us 4 when divided by the area of the triangle, 49in^2. Therefore, the answer is B, or that the area of the triangle is 49in^2 so she can create only 4 triangles.

the formula for area of a circle: pi * r^2
find the area of the larger circle using the radius of 18m, then subtract the area of the smaller circle using a radius of 13m
