Answer:
A
Step-by-step explanation:
Note
One thing you should automatically notice is that x is larger, much larger than 20. x is the hypotenuse of a right triangle
Formula
Sin(18) = opposite side / hypotenuse
Givens
Sin(18) = 0.30902
opposite = 20
hypotenuse = x
Solution
sin(18) = 20 / x Multiply both sides by x
x sin(18) = 20*x /x
x sin(18) = 20 Divide by sin(18)
x sin(18) / sin18 = 20/sin(18)
x = 20 / 0.30902
answer: x = 64.72

Answer:
Step-by-step explanation:
Given
Co ordinates of vertices(1,-6) and (-8,-6)
When two points is given then Length of two points is given by
Perimeter of rectangle is =26 units
Let the other side be x
thus
x+9=13
x=4 units
therefore to get the other two co ordinates
such that the length of that side is 4 units is
Horizontal distance will remain same only vertical distance will change in given co ordinates to obtain the remaining two co ordinates
To verify the above two distance between two points must be 13 units
First of all, let's make sure we know what a 'solution' is, so that when you
have it, you'll know it.
The 'solution' is a NUMBER. It's the number that 'p' must be, in order to
make the equation a true statement. There's only one of them.
<u>p - 15 = 13 - 6p</u>
Add 6p to each side: 7p - 15 = 13
Add 15 to each side: 7p = 28
Divide each side by 7 : <em>p = 4</em>
Was that so tough ?
