Find y................
Shalnov [3]

Answer:

y = 3

Step-by-step explanation:

Given the above right angled triangle, we would use a trigonometric ratio formula to find y.

Given angle = 30°

Hypotenuse = 6

Opposite side = y

Solve for y using the trigonometric ratio formula as follows:

sin(X) = \frac{opposite}{hypotenuse}

sin(30) = \frac{y}{6}

Multiply both sides by 6

sin(30)*6 = \frac{y}{6}*6

0.5*6 = y

3 = y

y = 3
