Find the missing pieces of the triangle round to the nearest tenth ​

Mathematics
1 answer:
loris [4]2 years ago
6 0

Answer:

Step-by-step 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
