3. A carpenters wish to build a brick garage with an angle of 140 of roof meet (refers to Figure 1). Figure 1. A brick garage with dual access points. A pillar is install in the center (blue line) in order to support the roof and to fit two single roller doors to the garage. Let the angle of elevation from base of the left wall to the top of pillar is 34°, see Figure 2. The angle of elevation from top of the left wall to the top of the pillar is 20⁰ Plar Left Wall b. Figure 2. Left frame of the garage Par Given that the height of pillar from the ground is 4 m. a. Calculate how far the left wall from the pillar is. Calculate the height of the left wall. C c. Find the area of this garage by consider the inner room's wide and the inner roof.
