I dont understand yer "quesshun"
yu sae it form triangel with x & y axises
That impli tu me a rite triangel with base along the x-axis & 1 side along y-axis.
then yu want a point on the diagonal tu go thru (3,4)
slope gotta be negativ, so line hit positiv side av both axisis
Draw lines thru (3,4) giv y-intersept=4*3*tangent(theta)
& x-intersept=3+4*sine(theta)
Area=(1/2)(x-intersept)*(y-intersept)
I'm tired now. Dont wanna du no more werk on this
