Question

What is the value of $Y$ in the triangle, if the shortest side is $10$? (Use $30-60-90$ degree triangle theorem)

• A. 40
• B. 30
• C. 20
• D. 10

Answer 1

Answer: (C)

20

Using $30-60-90$ degree triangle theorem, the sides are in the ratio $1:2:$ $\sqrt{3}$
Hypotenuse, $Y=2\times$ shortest side
$=2\times 10=20$
$Y=20$
