Change the numbers into improper fractions then subtract
Answer:
700 cubic ft
Step-by-step explanation:
25*4=100
7*100=700
answer
z = 100
opposite angles
when inscribed in a circle, the opposite angles of a quadrilateral add up to 180
so z + 80 = 180 and y + 120 = 180
solve for z
z + 80 = 180
z = 180 - 80
z = 100
