Question

∠A=30°, b=4cm   and  c=6cm,  then Δ=
answer with process​

Answer 1

Step-by-step explanation:

sin30°= 4/a

1/2=4/a

a=8

We know that, a triangle can be constructed if sum of its two sides is greater than third side.

i.e., in ΔABC, AB + BC > AC

Let a=AB, b=BC, c=AC

⇒ 8+4>6

⇒ 12 > 6, which is true, so ΔABC with given conditions can be constructed.
