How To Find The Area Of A Triangle, Given Only Two Angles And One Side?

Anonymous answered

If 2 angles and one side are known then one can find the area with the help of following formula

Area = (a^2(SinB x sinC)/(2 SingA)

Here
a = 15 (side)
A = 90 (right angle)
B = 25

So C= 180 - (A+B)
C = 180 - (90+25)
C= 65

Putting the value in formula you will get

Area = ((15)^2 (sin25 x sin65))/ (2sin90)
= (225(0.38))/2(1)
= 85.5/2

Area =42.75>>> answer

There seems to be some thing missing. It is because that two sides are needed to find the area. If one angle is given one can find it in anyway but it can't be done this way.
