Use the pythagorean theorem to find y.
a²+b²=c²
3²+4²=c²
9+16=c²
25=c²
c=5
y=5

All angles of a triangle form a sum of 180. We know there is 65 and 90 degree angles given to us. 
65+90+x=180
155+x=180
x=25

Given the following formula, solve for v.<br> s = 1/2a^2v + c
weeeeeb [17]

Since there is no initial condition, the exact value of v cannot be determined, but you can set the equation up for a general evaluation of the situation.

s = 1/2a^2*v+c

First you need to subtract c from both sides to get

s-c = 1/2a^2*v

then you can just divide both sides by 1/2a^2 to get v

(2(s-c))/a^2=v

when dividing a fraction, such as 1/2, make sure to keep in mind that you're really multiplying the flipped version, so that dividing by 1/2 means multiplying by 2.
