Help me please ASAP!!

The measure of angle A is:

m ∠ A = 53.13°

Step-by-step explanation:

Given

The length AC = 3 cm

The length BC = 4 cm

To determine

m ∠ A = ?

Using the trigonometric ratio

tan A = opposite / adjacent

From the right-angled triangle, as shown, it is clear that:

Thus, substitute opposite = 4 and adjacent = 3

tan A = 4 / 3

A = arctan (4/3)

A = 53.13°

Therefore, the measure of angle A is:

m ∠ A = 53.13°

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

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)
