50 points. right triangle abc has its right angle at c. ac=3 and bc=4. which trigonometric ratios are correct? select each correct answer. 1.) sinb= 3/5 2.) tanb= 4/3 3.) cosa= 4/5 4.) sina= 4/5 5.) tana= 4/3

sinB= 3/5 is correct

tanA= 4/3 is correct

and sinA= 4/5 is correct

hope this helps ^

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
