Trigonometry Unit Circle question (see photo)

1 answer:

5 0

The answer is Choice A: (cos(theta), sin(theta))

More specifically x = cos(theta) and y = sin(theta) make up the point (x,y) which is where point P is located. Because we have a unit circle, the equation of the circle is x^2+y^2 = 1. This leads to cos^2(theta) + sin^2(theta) = 1 which is the pythagorean trig identity.

What is the length of the apothem, rounded to the nearest tenth?

amid [387]

See the attached figure to better understand the problem

we know that
in the triangle ABC
<span>applying the Pythagorean theorem
AC</span>²=AB²+BC²
<span>AC=8 cm
AB=apothem
BC=9.4/2-----> 4.7 cm

AB</span>²=AC²-BC²-----> 8²-4.7²-----> 64-22.09------> AB²=41.91
AB=√41.91-------> 6.47 cm---------> 6.5 cm
apothem=6.5 cm

the answer is
6.5 cm
