Question

in the figure is abc =45° AB =6cm find bc​

Answer 1

Step-by-step explanation:

(a) Given, BC = 6 cm and ∠B= 45°

We know that, the construction of a triangle is not possible, if sum of two sides is less than or equal to the third side of the triangle.

i.e., AB + BC < AC

⇒ BC < AC – AB

⇒ 6 < AC-AB

So, if AC – AB= 6.9 cm, then construction of ΔABC with given conditions is not possible.

Answer 2

Step-by-step explanation:

In a triangle ABC

$tan = \frac{opposite}{adjacent}$

tan 45=6/bc

1 =6/bc

bc×1=6

bc=6 hope u understand my answer
