How to get a 22 degree angle in a right angle triangle?

1 answer:

4 0

One way would be to draw 2 perpendicular lines whose lengths are in the ration of the tangent of 22 degrees.

tan 22 = 0.4040

So draw a line AB of length 10 inches, then using a compass construct a perpendicular line at point A Then measure a length of 4.04 inches along this line to point C. Then join CB.

Answer:

none of the above

Step-by-step explanation:

The problem as written cannot have any of the solutions offered.

For any of those choices, the right side expression will be irrational. The left side expression will be rational for any rational value of x, so cannot be equal to the right-side expression.

The solution is an irrational number near ...

x ≈ 1.33682898582
