1. To find the distance across a river, a surveyor chooses points A and B, which are 200 feet apart on one side ofthe river. She then chooses a reference point C on the opposite side of the river and finds that m_BAC = 820 and m ABC = 520. Approximate the distance from A to C.

200 A B

since both sides equal, there are infinitely many olutions.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

1.30
