Step-by-step explanation:
This is a right triangle trig problem. The base of the right triangle is the distance that Donna if from the flagpole; the flagpole is the side opposite the reference angle which was given as 26, and we are looking for the height of the flagpole, h. The trig ratio that uses the side opposite over the side adjacent is the tangent ratio, specifically:
and
123tan(26) = h so
h = 60.0 rounded to the nearest tenth. But that is only the height from her line of vision and up, not the whole height. In order to find the whole height, we have to add in her height up to her line of vision which is 5.3 feet. Therefore, the height of the flagpole is
60.0 + 5.3 = 65.3 feet.
Hey there! I'm happy to help!
We'll call our weeks w and call our total savings s.
We have an initial $85 and then we add 7 every week. This means that we will be adding 7 for every week, so we will put this in our equation as 7w.
Therefore, our equation would be s=7w+85
Now, we plug in 8 for our w value to see how much money she will have after 8 weeks.
s=7(8)+85
s=56+85
s=141
Therefore, Aubrey will have saved $141 after 8 weeks.
I hope that this helps! Have a wonderful day! :D
