Answer:
Answer is 9.6
Step-by-step explanation:
From the illustration above. See attachment for interpretation of this illustration.
To find the part label a in the attachment which is the length of the foot of the guide wire from the ground to the palm tree, we apply the sine rule, which says
a/sineA = b/sineB
In this case
a = ? , A = 58° , b = 6ft, B = 32°
So
a/sine58 = 6/sine32
a/0.848 = 6/0.5299
a = 6*0.848/0.5299
a = 5.088/0.5299
a = 9.601 ~ 9.6

Answer:
307.5$
Step-by-step explanation:
150$. 105% of it added.
Since 105% is 1.05, multiply the percentage by the cost to get the money added.
150*1.05=157.5
Then ADD it to the price/savings.
150+157.5=307.5$
