Answer:
1 》let equal side be X and other side y
now, length of y= 2x sin teta/2
=12.3×sin42/2
=12.3 × sin21
=4.407

Answer:
The area of the sector (shaded section) is 29.51
.
Step-by-step explanation:
Area of a sector = (θ ÷ 360) ![\pi](https://tex.z-dn.net/?f=%5Cpi)
![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r = ![\frac{diameter}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bdiameter%7D%7B2%7D)
=
= 13 m
θ = 360 - (180 + 160)
= 360 - 340
= ![20^{o}](https://tex.z-dn.net/?f=20%5E%7Bo%7D)
Thus,
area of the given sector =
x
x ![(13)^{2}](https://tex.z-dn.net/?f=%2813%29%5E%7B2%7D)
=
x x
x 169
= 29.5079
The area of the sector (shaded section) is 29.51
.
