Two angles of a triangle have measures of 30° and 45°. What is the measure of the remaining angle?
Enter the correct answer in the box.

30+45+x=180(sum of all angles of triangle is equal to 180 degree)

75+x=180

x=180-75

x=105

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
