Question

in triangle abc if angle A is equal to 45 degree angle b is equal to 60 degree then find the ratio of its side​

Answer 1

The Law of Sines states that, for ΔABCΔABC, with a, b, and c the sides opposite each angle, respectively,

asinA=bsinB=csinCasin⁡A=bsin⁡B=csin⁡C

We also know that for any triangle, A+B+C=180°A+B+C=180°, so we know C=75°C=75°.

Thus, we know:

asin45°=bsin60°=csin75°asin⁡45°=bsin⁡60°=csin⁡75°

⟹a2√2=b12=c2√+6√4

Answer 2

Answer:

Step-by-step explanation:We know that sum of all three angles in a triangle is equal to 180 degree

45+60=105

180-105=75

3rd side is 75 degree

So the ratio is equal to 40:60:75

And then simplify
