How many feet tall is the taller tree?

16.33 feet

Step-by-step explanation:

17.5 / 11.25 = x / 10.5

x = 17.5 * 10.5 / 11.25 = 16.33

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
