The scale drawing shows two trees the actual height of the shorter tree is 3.9 m a find the scale of the drawing in the form of 1:n finf the actual height of the taller tree

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

you can use a^2+ b^2=c^2

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°

it will take 9 minutes
