OR MAT C42_WS_m1 App To support the back of the sofa, we have to use the shape as shown. Here, XY is parallel to X' Y. The given steps help to solve /a and /b. Check corresponds to the step with an error. the box that Step 1: /4 and 130° are vertically opposite angles, so 24 130° %3D Step 2: za and 4 are corresponding angles, so 4. Za = Z4 = 130° Y Step 3: za and /b are alternate exterior angles, so 130° zb = Za = 130° 2. 000
