Ab 5 4 Cm В€ A 30в° And В€ B 90в°

AB = 5.4 cm, ∠A = 30° and ∠B = 90°. Measure ∠C and side BC.

Answers:

Steps of Construction :
(1) Draw a line segment AB = 5.4 cm.

(2) At A construct an angle ∠A = 30°.
(3) At B construct an angle ∠B = 90°.
(4) AD and BE intersect each other at C.
(5) ∴ ∆ABC is the required triangle.
(6) On measuring ∠C = 60° side BC = 31 cm.
