Question

in the figure if angle acb =45°,ab=6cm find bc​

Answer 1

Step-by-step explanation:

so, the answer is

Answer 2

The length of BC = 6cm

Given

• Angle ACB = 45°
• AB = 6cm.
• BC = ?

   

   →In the given triangle AB is perpendicular.

  → BC is the base.

   

Using trigonometric expression

tanФ = Perpendicular/ Base

  tan 45° = 6/BC       (tan 45° = 1)

  1 =  6/BC

  BC = 6 cm
