What is a Triangle ?

A triangle is a polygon with three sides , angles and vertices.

It is given that ABC is a triangle such that

CAB = 90°

ABC = 30° and

AC = 9.3.

AB = ?

As the triangle is a right angled triangle

Trigonometric ratios can be used.

sin x = Perpendicular / base

sin 30 = AC / AB

(1/2) = 9.3 / AB

AB = 9.3 /0.5

AB = 18.6

Therefore the length of AB = 18.6 .
