I’m not quite sure how to solve this 30 60 90 triangle problem, any help?

12

Step-by-step explanation:

First, to find the side of the first triangle, divide by the square root of 3. so         6. Which is 2 radical(Square root) 3. To get the final side of the triangle, multiply by 2 which gets you to . To find X, multiply by which equals 12. The ratio to follow for 30, 60, 90 triangles is . the first being the short side, the second being the long side, and the third the hypotenuse.

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
