Answer:
Explanation:
- sum of inner angles of a triangle = 180 degrees
angle A = 180 - (90+23) = 180 - 113 = 67 degrees
- sin (23) = 0.390731
sin = opposite/hypotenuse
opposite = sin * hypotenuse
AC = 0,390731 * 34 = 13.3
- cos (23) = 0,920505
cos = adjacent/hypotenuse
adjacent = cos * hypotenuse
BC = 0,920505 * 34 = 31.3
