Johanna purchases a book for $14.95. There is a sales tax of 6.5%. How much is the final price with tax? What is the total? What
Nat2105 [25]
Okay so 6.5%  of $14.95 is 0.97175. That rounds to 0.97. And to get the total we just add 0.97 to 14.95. Our answer is 15.92. However if you don't want to round then you would add 14.95 and 0.97175 . This would give you15.92175. Hope this helps!

Veseljchak [2.6K]

Answer:

Step-by-step explanation:

First we know triangle WXY is an equilateral which means all its angles are 60 degrees.

Next we know triangle WZY is an isosceles so it has 2 angles that are equal to each other.  

Since angle Z is an obtuse angle. We can calculate the other angles which we will assume are equal because 138+138 is greater than 180 degrees.

180-138 = 42                

42/2 = 21              <-- divide by 2 because we know we're looking for 2 angles

For the angles of WXY.

60-21 = 39

Therefore

Angle I = 60

Angle 2 = 39

Angle 3 = 21

Angle 4 = 39

Angle 5 = 21
