Answer 2

is there an image

Answer 3

nope

Answer 4

dats weird to have no image

Answer 5

i would think u would need one

Answer 6

idk

Answer 7

do uk how to do this like at all

Answer 8

no, i dont understand how to do it

Answer 9

It is B. 58 because consider the right triangle ABC, with C as the right angle. The sides opposite those angles are a, b, c, where c is the hypotenuse. So if angle A is 32 then Angle B will be 90-32=58. For better understanding sin(A) = cos(90°-A) = cos(B) 90° -32° = B 58°
