In a rectangular triangle 
.
We have 
Therefore opposite = 3uints and adjacent = 4units.
We need the length of hypotenuse.
Use the Pythagorean theorem:
Substitute:

Answer:
log (448)
Step-by-step explanation:
3 log(4) + log(7)
We know that a log b = log b^a
3 log(4) + log(7)
log 4^3 + log 7
log 64 + log 7
We know that log a + log b = log (a*b)
log (64 *7)
log (448)
A. True. Summing any rational number with an irrational number leads to an irrational result. The proof is a bit lengthy so I'm leaving it out.
B. True. Adding p/q with r/s leads to (ps+qr)/(qs) which is rational. Keep in mind that q and s cannot be zero.
C. False. One counter example is sqrt(3)*sqrt(12) = sqrt(3*12) = sqrt(36) = 6. This shows the product of two irrational numbers, in this case sqrt(3) and sqrt(12), multiplying to get a rational result 6 = 6/1.
D. True. Multiplying p/q and r/s leads to (p*r)/(q*s) which is rational. Keep in mind that q and s cannot be zero.
