Answer:
19) 28°
20) 60°
21) 17°
Step-by-step explanation:
19)
Supplementary angles:
(x + 12)º + 140º = 180º
x + 12 + 140 = 180
x = 180 - 140 - 12
x = 28º
20)
Angles at a point:
(- 24 + x)° + 24° + 300° = 360°
- 24 + x + 24 + 300 = 360
x = 360 - 300
x = 60°
21)
Vertically opposite angles:
(1 + 3x)° = 52°
1 + 3x = 52
3x = 52 - 1
3x = 51
x = 17°
Answer:
The total area (including the area of the circle) would be 16 × 16 = 256 square centimetres.
The area of the circle would be (taking the value of pi as 3.14) is 200.96 square centimetres
The area of the shaded region would be 256 - 200. 96 = 55.04 square centimetres
