Question

In triangle ABC,m angle b=90°, m angle C=30°, m angle A=60° and AB=6 cm Then find AC=? who will solve this answer I will mark them BRAINLIEST and 5 star tooo​

Answer 1

Answer:

As perimeter of ΔADC= perimeter of ΔADB

Let length of AD be

′

l

′

then,

l+x+80=60+l+(100−x)

⇒20=100−2x⇒x=40cm

∴ length of BD=(100−x)=60cm

solution

I hope this helps you

Answer 2

Answer:

think so 12

Step-by-step explanation:

as it is a right angled triangle

sin 30 = AB/AC = 6/AC and sin 30 = 1/2

1/2 = 6/AC

AC = 6 x 2 = 12
