10/16=x/124
X=(124)(10)/(16)=1240/16=80
Answer:
a=9in
Step-by-step explanation:
Pythagoreans Theorem
a^2+5.6^2=10.6^2
a^2+31.36=112.36
a^2=81
(take square root of both sides)
a=9
Let x = number of students in each of the remaining rows
266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13
