Question

From given figure, In ∆ ABQ, If AQ = 8 cm. then AB =
angle 30°
angle 90°​

Answer 1

Answer:

can u write the values properly

Answer 2

Given :  ∆ ABQ

∠B = 90°

∠Q = 30°

AQ = 8 cm

To Find : AB

Solution:

Sin (angle) = Perpendicular / hypotenuse

Sin ∠Q  = AB/AQ

=> Sin ( 30°)  =  AB/ 8

=> 1/2  = AB/8

=> AB = 8/2

=> AB = 4  cm

AB is 4 cm
