In the unit circle the hypotenuse of the triangle formed is equal to radius of circle , which = 1. The point on the circle formed by the intersection of the hypotenuse is (cos q , sin q) where q is the angle between the x axis and the hypotenuse. As the hypotenuse = 1 the opposite and adjacent sides of the triangle < 1 so sin and cos of q must both be <= 1.
A/B - 90° | C - 42° | D - 48 | E - 132
Answer:
I think the answer to the first question is "B"
and the second one is "D"
Step-by-step explanation:
Step-by-step explanation:
- <FGL is acute
- <HGF is acute
- <KGH is acute
- <KGF is obtuse
- <KGL is obtuse
- <HGL is right
value of complement is 90 and obtuse angle refers to angles that is above 90. complement can be said right angle but not obtuse.
- The sum of two acute angles sometimes results in an obtuse angle.
- Two obtuse angles are never supplementary.
- The sum of two right angles always results in a straight angle.
