Step-by-step explanation:
In ∆ABC, if <A is 90° and <B is 45° then hypotenuse is BC.
Now,
Cos B= base/height
Cos B= AB/ BC
BC= AB/cos 45°.
Equal payments of $91.00 for 30 wks
at 8 wks she would need $728.00 all together
(30*6) / (2*5) = 180/10 = 18 tiles
A. because whole numbers can’t be a fraction or negative
