Answer:
43.60°
Step-by-step explanation:
We can solve the triangle using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.
Considering triangle ΔDEF, where ∠F=90°, FE = 21, DF = 20, and ED = 29
As such, with respect to angle E, ED is the hypotenuse, DF is the opposite side and FE is the adjacent side
Cosine ∠E = 21/29
∠E = cos-1 0.724137931
∠E = 43.60° to the nearest hundredth
Okay, so we need to find the price of the original shirt and the discounted shirt with the 5% tax.
5% (into a real number) is .05
Multiply 20.98 and 15.48 by .05
20.98*.05= 1.049 I am going to round to 1.05
15.48*.05= 0.774 I am going to round to .75
Now we know the prices of both, so we subtract them by each other.
20.98+1.05= 22.03
15.48+.75= 16.23
22.03-16.23= 5.80
But since we rounded the numbers, I would go with choice D.
Hope this helps!
