When working with logarithms, remember that a subtraction sign means you can divide.
log(400) - log(4) can be turned into log(400/4), which is further simplified to log(100).

Help pleassssssssssssseeee

DiKsa [7]

Answer:

27in, 36in, 45in

Step-by-step explanation:

$a = 27 \\ b = 36 \\ c = 45$

${c}^{2} = {a}^{2} + {b}^{2}$

$c = \sqrt{ {a}^{2} + {b}^{2} }$

$45{ = }^{?} \sqrt{ {27}^{2} + {36}^{2} }$

$45 { = }^{?} \sqrt{729 + 1296}$

$45 { = }^{?} \sqrt{2025}$

$45 = 45$

HELP ASAP how do I solve this problem

puteri [66]

Answer:

C. 5/3 (5 sqrt 3) (8.66...)

Explanation:

You would use the SohCahToa to find out side x.

First, label your sides (10 is hypotenuse, x is the opposite, and blank side is the adjacent).

Second, figure out which part you have to use (Sin, Cosine, or Tangent). A good way to tell is of you have the missing side on top of the fraction, makes things easier.

Third, once you figure that out then plug stuff in...

Sin(theta) = O/H
Sin(60) = X/10
10sin(60) = X
8.66... = X
