recall that, log <--- with no apparent base, implies base10, so you can just plug that in your calculator
for the change of base rule, it doesn't really matter what base you use, so long is the same above and below, it just so happen, that we used base10 in this case, but could have been anything, same result.

Answer:
24°:48°:108°
Step-by-step explanation:
Since the sum of angles in a triangle is 180°, we can do 180÷15 to find the degree for 1 in the ratio. 180÷15 = 12.
12°×2 = 24°
12°×4 = 48°
12°×9 = 108°
The ratio is 24°:48°:108°
Answer:
m2 = - 1
Step-by-step explanation:
Subtract x from both sides of the equation
-y = - x - 3
Divide by - 1
-y/-1 = -x/-1 - 3/-1
y = x + 3
The slope of the line we were given is 1. The 1 is in front of the x
m1 * m2 = - 1
m1 = 1
1*m2 = - 1
m2 = - 1
