The measure of acute angle A to the nearest tenth of a degree is 51.2°
From the given information, we are to determine the measure of the angle.
The angle we are to determine its measure is acute angle A
From the given information, we have that
sin A = 0.7793
Thus,
A = sin⁻¹(0.7793)
Using calculator
A = 51.1965°
A ≅ 51.2°
Hence, the measure of acute angle A to the nearest tenth of a degree is 51.2°

Answer:
57 kilometers a day.
Step-by-step explanation:
I just divided 513 by 9 and got that.
We can get two different equations from this:
3x = 18
and
3x = -18
So:
x = 6, x = -6
x = {6, -6}
20
IF you are asking why it is because 50-32=18 than you do 18/.90 which equals 20 so there you go thanks make brainliest
