In the picture above, it is known that the CD arc length = 8 cm, the APB area = 24 cm, and the CPD area = 20 cm. Find the arc length AB

the answer will be that CD is parallel to AB and aseer will be 8

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
