Step-by-step explanation:
More than one triangle can be formed by three angles measuring 75°, 45° and 60°. Solution : We know that, The sum of the measures of all angles of a triangle should be equal to 180°. Hence, the angles 40° , 50° and 60° cannot form a triangle as their sum is 150°.
X=real height of the tree
1 cm / 0.75 m=6.5 cm / x
x*1cm=0.75 m*6.5 cm
x=(0.75 m*6.5 cm) / 1 cm=4.875 m
therefore: the real height of a tree is 4.875 m,
