Answer:
AC = 18
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = , then
cos30° = =
=
=
( cross- multiply )
2 AC = 12 ×
= 12 × 3 = 36 ( divide both sides by 2 )
AC = 18
Answer:
The area of the sector of the circle is approximately
Step-by-step explanation:
The given parameters of the circle having a shaded sector are;
The radius of the circle, r = 4 meters
The measure of the arc bounding the sector = 135°
The area of a sector of a circle, 'A', is given as follows;
Therefore, the area, 'A' of the given sector of the circle, is given as follows;
The area of the sector of the circle, with radius 4 cm and bounded by an arc, A ≈ 18.82 cm².
