In right triangle ABC, the measure of angle A is 25 degrees, angle c is 90 degrees, and AB = 1. what is the length of AC?

b = 0.9

Step-by-step explanation:

first you find angle B: 180-90-25=65

then you will do law of sine - sin A/a=sin B/b=sin C/c

sin (90) / 1=sin 65/b

sin (90) * b=sin (65) * 1

sin (90) * b=0.9

b=0.9/sin (90)

b = 0.9
