Answer:
1. x = 12
2. x = 18
Step-by-step explanation:
1. Angle ABD + angle CBD = 180 degrees
(4x+6) + (11x-6) = 180
4x + 6 + 11x - 6 = 180
4x + 11x = 180
15x = 180
x = 12
2. 2x + 3x = 90
5x = 90
x = 18
The figure can be separate into a triangle, a rectangle and a trapezium.
<u>Triangle:</u>
Area = 1/2 x base x height
Area = 1/2 x 16 x (25 - 4) = 168 units²
<u>Rectangle:</u>
Area = length x Width
Area = 16 x 4 = 64 units²
<u>Trapezium:</u>
Area = 1/2 (a + b) x h
Area = 1/2 (25 + 15) (10) = 200 units²
Total Area = 200 + 64 + 168 = 432 units²
Answer: 432 units²
