Answer:
AC = 2.87
Step-by-step explanation:
well to start we have to know the relationship between angles, legs and the hypotenuse in a right triangle
B = 35°
h: hypotenuse = 5
o: opposite = AC
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, hypotenuse, opposite)
we look at which meets those data between the sine, cosine and tangent
is the sine
sin α = o/h
Now we replace the values and solve
sin 35 = o/5
0.573576 = o / 5
0.573576 * 5 = o
2.86788 = o
round to the nearest hundredth
o = 2.86788 = 2.87
AC = 2.87
