Answer:
x ≈ 33.0
Step-by-step explanation:
The third angle in the triangle is
180° - 70° - 76° = 180° - 146° = 34°
Using the Sine rule in the triangle
= ( cross- multiply )
x × sin34° = 19 × sin76° ( divide both sides by sin34° )
x = ≈ 33.0 ( to the nearest tenth )
500 is what you already have if it grows 2.75% a month you multiply it by the month and add it to 500
500+2.75%m
