angle D=90°
angle A=angle B = 30°
hypotenuse=100 m
line BC=line CA
find AD
this is a trigonometry question ​

Answer 1

Answer:

50 m

Step-by-step explanation:

Given,

B = 30°

Values : -

Sin 30° = 1 / 2

In Δ ABD,

Sin B = AD / AB

Sin 30° = AD / 100

1 / 2 = AD / 100

2 × AD = 1 × 100

AD = 100 / 2

AD = 50 m
