Answer 1

Answer:

answer is 5 required unit

Step-by-step explanation:

since the triangle is right angled we can use trigonometric ratios.

sin 30 = opposite side/hypotenuse

sin 30 that is 1/2 is equal to opp.side (x) divided by hypotenuse (10cm)  

1/2 = x/10

cross multiply 2x=10  

and x=10/2

and the answer is 5 required unit.

Answer 2

HEY Buddy....!! here is ur answer

Given that : Hypotenuse = 10 and angle = 30°

As we know that :

$\sin\alpha = \frac{perpendicular}{hypotenuse} \\ \\ = > \sin30° = \frac{x}{10} \\ \\ = > \frac{1}{2} = \frac{x}{10} \\ \\ As \: we \: know \: that :\: \sin30° = \frac{1}{2} \\ \\ = > x = \frac{10}{2} = 5$

So, the side will be 5

I hope it will be helpful for you...!!
