Question

in triangle ABC angleB=90°,angleA=30° AC=14 then find AB and BC​

Answer 1

Answer:

7√2 and 7

Step-by-step explanation:

given : angle B= 90°

angle A =30°

angle B = 60°......

remaining angle of triangle

a/c to 30-60-90 theorem

we know the side opposite to60° is √3/2 of hypotenuse

so, AB = √3/2 of AC

=√3/2 × 14

AB = 7√2 units

we know that side opposite to 30° is 1/2 of hypotenuse

so, BC = 1/2 of AC

=1/2 × 14

= 7 units
