Answer:
A = 23.6 units^2
Step-by-step explanation:
Let the base be 8 (as shown).
Find the height of the triangle: Find the supplement of the 100 degree angle; it is (180 - 100), or 80 degrees. The side "opposite" this 80-degree angle is the height of the triangle:
height
sin 80 degrees = ---------------
6
and so the height of the triangle is h = 6 sin 80 degrees, or 5.91 units.
The area of the triangle is found using A = (1/2)(base)(height), which here amounts to:
A = (1/2)(8 units)(5.91 units), or
A = 23.64 units^2, or A = 23.6 units^2
Francisca raises 76.50 and Elizabeth makes 43.50 together they makes 120
It is: x + 27 = -12
x = -12 - 27
x = -39
In short, Your Answer would be -39
Hope this helps!
Answer:
Step-by-step explanation:
Given: 
; find x and y.
Let's start with finding x first. Let's distribute the left side of the equation.
Let's move everything we can to the left side of the equation. Some things will cancel out.
Now, let's move the term that includes 
to the left side of the equation. Everything else should be moved to the right.
Let's get rid of the negative sign in front of by dividing both sides by -1.
To get completely isolated, divide both sides by 
.
Simplify.
Let's solve for y. We will start with the distributed and simplified equation to make it easier.
Now, let's move the term that includes 
to the left side of the equation. Everything else should be moved to the right.
Again, let's get rid of the negative sign in front of the by dividing both sides by -1.
To isolate y, divide both sides by z.
Simplify.
