Someone help me with this. I forgot my notes in class
Nonamiya [84]

Answer:

see explanation

Step-by-step explanation:

Since AB = BC the the triangle is isosceles and thus

∠ A = ∠ C = 8x

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

44x + 8x + 8x = 180, that is

60x = 180 ( divide both sides by 60 )

x = 3

Thus

∠ A = ∠ C = 8x = 8(3) = 24°

∠ B = 44x = 44(3) = 132°

solve for the indicated variable. include all of your work in your answer. submit your solution. P=2L+2W; for L.
allochka39001 [22]
We have this equation:

P=2L+2W

So, we need to solve this equation for L. Then we sum -2W in each member of the equation, like this:

P-2W=2L+2W-2W
P-2W=2L

Then, dividing the equation by 2:

\frac{P-2W}{2}=L

Finally, let's order this equation:


L=\frac{P-2W}{2}
