Answer: option C
Step-by-step explanation:
The diagram of the triangle is shown in the attached photo. The triangle is a right angle triangle ABC
Assuming the given angle is #,
Recalling the trigonometric ratio,
tan # = opposite / adjacent
If tan # = 4, it means
opposite / adjacent = 4/1
Therefore, opposite = 4 and adjacent = 1
Applying Pythagoras theorem,
Hypotenuse^2 = opposite ^2 + adjacent ^2
Hypotenuse = AC
Opposite = 4
Adjacent = 1
AC^2 = 4^2 + 1^2 = 17
AC = ± √17
To determine cos #, we would apply another trigonometric ratio,
Cos# = adjacent /hypotenuse
Cos# = 1/±√17
Cos # =-1 /√17 or 1/√17
Answer:

Step-by-step explanation:
Answer:
2=1
Step-by-step explanation:
So, he deposited 17 dollars, ( 4 ) 5 dollar bills, and 6 twenty dollar bills.
5 + 5 + 5 + 5 = 20
20 x 6 = 120
120 + 20 = 140
140 + 17 = 157
He deposited a total of <u>157 dollars.</u>
hope this helps!
5x/3=35
5x = 35*3=105
x= 105/5 = 21
double check 5 x 21 = 105
105/3 = 35
