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
