The formula for the area of a triangle of base b and altitude h is A = (1/2)(b)(h).
Here, b = 18 cm and h = 9 cm. Thus, the desired area is:
(18 cm)(9 cm)
A = ----------------------- = 81 cm^2
2
This problem gives you more info than is needed to solve it. The area of the given triangle is 81 cm^2.
Evaluation of square root 169 = 13, so 10 + 13 = 23
Answer:
Step-by-step explanation:
If APB is measured in radians, then the arc length AB = APB(r) where r is the radius of the circle.
