The picture illustrates how to form the required angles. Graph paper is best to use, along with a straight edge or ruler. A protractor is not needed. The angles at P, Q and R are right angles, and you can make these using a set square if you are not using graph paper. The line measurements can be any units as long as the horizontal and vertical measurements use the same unit.
Some of the angles are marked. If you position the points A, B and D accurately you will find the following angles:
AOQ=125; the angle of 100 is shown on BO produced and AOB=AOQ-BOP=125-45=80; DOQ=AOR=55, and AOD=AOQ-DOQ=125-55=70. So the angles you need are AOQ=125 (shown), AOB=80 and supplementary angle 100 (shown) on BO produced, AOD=70. (AOQ is an approximation with 0.01% error.)
