Two trees are standing on flat ground. 20m
7 m
15 m
The height of the smaller tree is 7m. The distance between the top of the
smaller tree and the base of the taller tree is 15 m.
The distance between the top of the taller tree and the base of the
smaller tree is 20 m.
a Calculate the horizontal distance between the two trees.
b Calculate the height of the taller tree.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
