Find the diagonal of a cube if its side equals 5. when applicable, simplify radicals and show all of your work.

7.0711

Step-by-step explanation:

The diagonal of a square of side of length a is a√2.

Here, the length of the square is given as: 5 units.

So, the length of the diagonal is 5√2 units.

But √2 = 1.4142.. (Approx.)

So, the length of the diagonal, d = 5 X 1.4142.

This is equal to 7. 0711.

So, the answer is 7.0711 units.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
