Answer 2

Answer:

AC= 8/√3

BC= 4/√3

Step-by-step explanation:

Since it is a rt. angled triangle,

tan θ= AB/BC.

tanθ=4/BC

tan 60° = 4/ BC

√3 = 4 / BC

BC= 4/√3

BC= 4√3 / 3 units.

∴AC²=AB²+BC²

AC²=4²+ (4/√3)²

AC² = 16 + 16 / 3

AC² = 48+16 / 3

AC² = 64 / 3

AC=√(64/3)

AC= 8 /√3

(or)

AC = 8√3 / 3.
