Question

Construct a right triangle ABC such that BC =4 cm and the hypotenuse makes an angle of 30 degree at B. Verify that AB=2AC

Answer 1

Since ABC is a right angle triangle and hypotenuse make 30° angle with B here BC is thr base AC is the perpendicular then by trigonometry
sinB= AC/AB
sin30°=AC/AB
1/2=AC/AB
AB=2AC
