Answer:

x = 16  y = 22.627 (or 16\sqrt{2)

Step-by-step explanation:

cos(45) = 16/y

y = 16/cos(45)

y = 22.627

tan(45) = 16/x

x = 16/tan(45)

x = 16

*this can also be found because we know this is a right triangle with two angles of 45 degrees. This means that both sides will be equal so x will be 16 and the diagonal will be 16 root 2 (22.627)

Ritz can eat 8 apples in 15 minutes.how long does it take ritz to eat 16 apples at the same rate.
zhannawk [14.2K]
We can answer the problem using a rule of three, simple, direct proportion and also using fractions. First the rule of three:
8 apples ------> 15 min
16 apples ----> x

x = (16)(15)/8
x = 30
therefore he can eat 16 apples in 39 minutes.

We can also equate fractions like so:
8/15 = 16/y
and solve for y:
y = 15*16/8
y = 30
