Question

In triangle ABC angle A is 3x° angle B is 2x° angle C x° and AB is 12 cm then what will be the lenght of AC

Answer 1

Step-by-step explanation:

Sum of angles in a triangle=180°

3x°+2x°+x°=180°

6x°=180°

x°=30°

angle A=90° ;angleB=60°;angkeC=30°

given AB=12cm

By applying trigonometric ratios

tanC=AB/AC

1/root3=12/AC

AC=12root3 cm

Hope this helps
