Question

In triangle ABC, Angle A= 90°,ngle B= 60°,BC= 17cm,then AB=​

Answer 1

Answer:

If possible, mark me as brainliest ( your choice but)

AB = 8.5 cm

Step-by-step explanation:

in triangle ABC, given we have A = 90, B=60 and BC = 17

by angle sum property, C = 30,

so, AB is the opposite side.

so by sin, opp / hyp = sin 30

               AB / BC = 1/2

               AB / 17 = 1 / 2

               AB = 17/2

               AB = 8.5 cm
