Suppose the leg AB 38, and the leg BC 46.Draw the leg AB in length 38 ; from B erect a perpendicular to C in length 46 ; and draw a line from A to C. Fig. 34. *>• … PROBLEM XIII. To make an oblique angled tri-angle, the angles and oneside being given. Fig. 34. Suppose the side BC 98 ; the angle at B 45° 15, the angleat D 108° 30, consequently the other angle 26° 15. Draw the side BC in length 98 ; on the point B make anangle of 45Q 15; on the point C make an…
