Answer:
y = 10
x = 64
Step-by-step explanation:
the equations containing y are adjacent angles in a parallelogram, meaning that they are supplementary, so we can create an equation:
5y + 2 + 12y + 8 = 180
solve this to get y = 10
the equation for x would be 2x + 5y + 8 = 180 because these angles are also supplementary
solve this to get x = 64
2=5-3 so the answer is (2, 5)
Mrs. Beachy would drive 53mph. How I did it:954÷18(18 can't go into 9.... 95?)Yes, 5 times.954÷18= 5 -(Okay... 95-90 is 5, drop the four... 54?)18x3 is 54!954÷18=54! So the answer is 54mph (Right? I am sure I did that right...)
Answer:
Advantages of mathematical models are they are useful and easy to prodce allowing faster decision making. They can help us to grow our understanding of the real world and they enable us to be made as well as help provide to understand the exact condition of stability for the considered system.

Answer:
Step-by-step explanation:
Left Hand Side
Change to sin(theta) and cos(theta)
csc(theta) = 1/sin(theta)
cot(theta) = cos(theta)/sin(theta)
1/sin(theta) - cos(theta)/sin(theta) Put over Sin(theta) Common denominator
[1 - cos(theta)] / sin(theta) Multiply numerator and denominator by 1 + cos(theta)
(1 - cos(theta)(1 + cos(theta) ) / sin(thata)*(1 + cos(theta))
(1 + cos(theta)(1 - cos(theta)) = 1 - cos^2(theta)
sin^2(theta) / (sin(theta)* ( 1 + cos(theta)
sin(theta) / (1 + cos(theta) )
Right hand Side.
See Above.
