Likewise the Vprojection is found to fallat h. Note that if the… … EXERCISE SHEET X Take P at the right border line. No P projections are required. 1. The point a (72, 6, 4) is given. The line oft is 10 units long andslopes upward and forward from a, making an angle of 30° with H andan angle of 45° with V. Find its projections. (Two solutions.) 2. The point c (48,…
