The perimeter of the semi-circular disc of radius 10.5 cm is 54 cm.
It would be called a mess up on ur paper
Here, 4x + x =180 [ Supplementary angles ]
5x = 180
x = 180/5
x = 36
In short, Your Answer would be Option C
Hope this helps!
The first thing we need to do is use tan to find x. If the original angle of depression is 7 degrees, then the angle from the cliff to the bow of the boat is 90-7=83 degrees. Thus,<span>tan83 = <span>d / 150</span></span>or we can express it like this:<span>d =150 tan 83 ≈ 855.2</span><span>where d is the total distance from the boat to the cliff when the angle of depression is 7 degrees. Hope this helps a lot</span>
well, we know the "sum" of both angles is 90°, notice the rectangle in the corner, so we can say that the angles are simply complementary angles, thus
