A right triangle has one 90 angle.
The sum of the three angles of any triangle is equal to 180 degrees.
180-90= 90 degrees.
The answer is C.

Answer:
2
Step-by-step explanation:
Maybe they got confused or could not read her handwriting well because im pretty sure it is 2
Here is some thoughts on this:
cos 57 = sin (90-57) = sin 33
so cos 57 . cosec 33 = cos 57 / sin 33 = sin 33 / sin33 = 1
2 cos 60 = 2 * 1/2 = 1
so the last 2 parts work out to 0
now we have to find cos 70 / sin 20
sin 20 = cos 70 so this comes to 1
so finally the answer is 1
