THE HEIGHTTo find the height, use trigonometry ratio (tan) of 60°

= tan α
plug in the numbers

= tan 60°

= √3
move 10 to the right side
height = 10√3
The height is 10√3 cmTHE AREATo determine the area of a triangle, use the following formula

b stands for the base, h stands for the height
plug in the numbers
a = 1/2 × b × h
a = 1/2 × 10 × 10√3
a = 5 × 10√3
a = 50√3
The area is 50√3 cm²
