Ijust need a confirmation that my answer is right? find side ac. round to the nearest hundredth. the angles are: angle a = 40°, angle c = 90°, and angle b = 50°. side ba (the hypotenuse) = 3 cm. i did this: cos40° = ac/3 3cos40° = ac ac = -2.08, but a length can't be negative am i doing something wrong? or do i just write 2.08? i can't remember.

∆red ≅ ∆ by rule will give brainiest if possible
