Question

in triangle abc angle a = 60 degree angle b = 90 degree angle c = 30 degree if ab = 6cm find ac​

Answer 1

Step-by-step explanation:

in triangle abc

angle a = 60°

angle b = 90°

angle c = 30°

ab = 6cm

there is angle B is 90 degree so we can use trigonometric terms

sin c = ab/ac

sin 30° = 6/ac. [:: given angle c = 30°]

1/2 = 6/ac. [:: sin30 = 1/2]

ac = 12cm
