Answer:
<h2>
i) Angle AOC is 95° </h2>
Reason:- Angle AOC is equal to Angle DOB since they are Vertically Opposite Angles.
<h2>
ii) Angle BOC is 85°</h2>
Reason:- Angle AOC + Angle BOC - 180° (they lie in a straight line so they are a linear pair. Sum of the angles will be 180°)
Angle AOC is 95°, So:-
95° + Angle BOC = 180°
Angle BOC= 180° - 95°
<h3><u>
Angle BOC = 85°</u></h3>
<u></u>
<h2>
iii) Angle DOE is 17°</h2>
Reason:- Angle AOE+ Angle DOE+ Angle DOB = 180° (they lie in a straight line so they're a linear pair. Sum of the angles will be 180°)
So,
68° + Angle DOE+ 95° = 180°
163° + Angle DOE = 180°
Angle DOE= 180° - 163°
<h3><u>
Angle DOE is 17°</u></h3>

Size small shirts: 18, 36, 63, 1800
Size large shirts: 4, 8, 14, 200
Step-by-step explanation:
For every 9 small, there is 2 large, therefore if there is 18 small, then there is 4 large because there are two 9s in 18.
Answer:
Larger shaded area = 48pi m^2 and
the small circle has area 4pi m^2.
If you require the as decimal values they are
150.80 m^2 and 12.57 m^2 to the nearest hundredth.
Step-by-step explanation:
The area of the whole circle = pi r^2 = pi 8^2 = 64pi.
The area of the middle sized circle = pi 4*2 = 16pi.
So the area of the larger shaded region
= 64pi - 16pi = 48pi m^2.
The area of the small circle = pi r^2 = 2^2 pi = 4pi m^2.
