Answer:
R theta 1 = 20 x
R theta 2 = 11 x - 6
R ( theta 1 + theta 2) = 31 x - 6 adding equations
R pi = 31 x - 6 since theta 1 + theta 2 = 180 deg
x = (R pi + 6) / 31
This equation depends only R
If one lets R be one then x = (pi + 6) / 31
This would give x = .29489 rad for the value of pi is deg
The numerical value of x appears to depend on the value of R
Just split it in to three rhombuses and then split each rhombus in half.
You will now have six triangles
Answer:
12
Step-by-step explanation:
The first thing you would want to do is to draw it out. Once you've drawn it out, you want to add the "imaginary lines" so the trapezoid will form into a rectangle. Then find out the area which is L * W. The area for the rectangle is 20.
Finally you want to take those imaginary pieces and find the area of those. Which would be three and then you want multiply by two since there is two of them. The last thing you need to do is subtract the six from 20.
<u>Therefore the answer is 12.</u>
