For each of the following triangles, solve for B and use the results to explain why the and triangle has the given number of solutions.A = 60, b = 18 m, a 16 m; two solutions
MAT 211 Lecture 3 Section 15.1 (Cont.) Position of Two Planes in the xyz plane can: be parallel OR intersect in a line (called a line of intersection) Ex.: At which line the plane z= 3x2y+6 and the yz coordinate plane intersect yz coordinate plane> x=0 z= 2y+6 Ex.: At which line the plane z= 3x2y+6 and the xz coordinate plane intersect xz coordinate plane> y=0 z= 3x+6 Ex.: At which line the plane z= 3x2y+6 and the xy coordinate plane intersect xy coordinate plane> z=0 z= 3x2y+6 Ex.: Homework Problem #13.) z= f(x,y)= 13x+2y xint.: y=0, z=0 0= 13
