The sum of the angles of a triangle is 180°.
The angles you know are 28° and 36°, so you can do this to find ∠B:
∠A + ∠B + ∠C = 180°
or 28° + ∠B + 36° = 180° Add 28 and 36
64° + ∠B = 180° Subtract 64 on both sides
∠B = 116
Answer:
1) 90
2) 38
Step-by-step explanation:
1) look at the attached diagram
As you can see, the floor and the wall must meet at a 90° angle.
2) Perimeter of office: 10 + 12 + 10 + 12 = 44
Subtract the door and windows' lengths:
44 - 3 - 3 = 38 ft.
