Shortest side (a) = 58
middle side (b) = 64
longest side (c) = 77
the 3 sides a + b + c = 199
b = a + 6
c = a + 19
substitute your new values for b & c into your original formula, so:
a + (a+6) + (a+19) = 199
3a + 25 = 199
3a = 174
a = 58
then substitute 58 into your b & c formulas to figure out the rest
b = a + 6 = 58 + 6 = 64
c = a + 19 = 58 + 19 = 77

Answer:
$817.50
Step-by-step explanation:
Hello Matt7151!
To find the total amount, we will first need to find how much tax.
We can express 9% as the fraction 
.
× 750 = 67.50
So she's paying $67.50 sales tax.
750.00
67.50
-------------------
817.50
So Debra's really paying $817.50.
Thus, the answer is 
.
Answer:
The value of sin X = 12 / 13
Step-by-step explanation:
Given
- The side opposite to angle ∠X = 12
To determine
sin X = ?
We know that the trigonometric ratio involving sin Ф such as
sin Ф = opposite / hypotenuse
Here:
- The side opposite of Angle X = 12
so substituting Ф = X, opposite = 12 and hypotenuse = 13 in the equation
sin Ф = opposite / hypotenuse
sin X = 12 / 13
Therefore, the value of sin X = 12 / 13
