Answer:
Impossible to solve this problem with the info given
Step-by-step explanation:
The altitude of the triangle is 20.1 according to the drawing. That is a leg of the right triangle and 18 is the length of the hypotenuse. But, the hypotenuse of a right triangle must be longer than either leg. So, the 20.1 in the drawing must be incorrect. Or the 18 is incorrect.
Answer:
Option C.
Step-by-step explanation:
The equation that models the position of the weight and time will be a sine wave.
y = A sin(bt)
where A = amplitude of the wave
b = time period for a complete oscillation
Since b = ![\frac{2\pi }{t}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%20%7D%7Bt%7D)
It has been given in the question, Time period t = 3 sec.
b = ![\frac{2\pi }{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%20%7D%7B3%7D)
Amplitude A = 2 in.
Now we plug in the values of amplitude and time period in the standard equation.
y = ![2sin(\frac{2\pi }{3}\times t)](https://tex.z-dn.net/?f=2sin%28%5Cfrac%7B2%5Cpi%20%7D%7B3%7D%5Ctimes%20t%29)
y = ![2sin(\frac{2\pi t}{3})](https://tex.z-dn.net/?f=2sin%28%5Cfrac%7B2%5Cpi%20t%7D%7B3%7D%29)
Option C. is the answer.
The question is an illustration of a division model.
The boxes will be completed with: 1650, 231, 50 and 7
The expression is represented as:
![\mathbf{1881 \div 33}](https://tex.z-dn.net/?f=%5Cmathbf%7B1881%20%5Cdiv%2033%7D)
Express 1881 as 1650 + 231.
![\mathbf{1881 \div 33 = (1650 + 231) \div 33}](https://tex.z-dn.net/?f=%5Cmathbf%7B1881%20%5Cdiv%2033%20%3D%20%281650%20%2B%20231%29%20%5Cdiv%2033%7D)
Split
![\mathbf{1881 \div 33 = 1650 \div 33 + 231 \div 33}](https://tex.z-dn.net/?f=%5Cmathbf%7B1881%20%5Cdiv%2033%20%3D%201650%20%5Cdiv%2033%20%2B%20231%20%5Cdiv%2033%7D)
Evaluate each division
![\mathbf{1881 \div 33 = 50 + 7}](https://tex.z-dn.net/?f=%5Cmathbf%7B1881%20%5Cdiv%2033%20%3D%2050%20%2B%207%7D)
![\mathbf{1881 \div 33 = 57}](https://tex.z-dn.net/?f=%5Cmathbf%7B1881%20%5Cdiv%2033%20%3D%2057%7D)
The above illustration means that, the boxes will be completed with the following numbers

Answer:
50 degrees
Step-by-step explanation:
You can see that angle ADC is composed of angle ADB and angle BDC
Angle ADB is 38 degrees and angle BDC is 12 degrees
Therefore angle ADC is 50 degrees
Angle ADC is opposite from angle ABC so they are congruent.
So angle ABC is 50 degrees
I have no clue I just have to answer this to get my math test done so I don’t fail lol
