Answer:x=6
Step-by-step explanation:
So if y is 0, that’s 8(y) which is 0. That means the equation is 2x=12, which means x is 6
My comments don’t work! But it’s (6,0)
Let's apply the law of sine to calculate angle C
sin(81)/26 = sin(C)/28
0.1646 = sin(C)/28 and sin(C) =1.063. Sine sin(α) cannot be > than 1, so this triangle is invalid
Subtract 30, then factor the equation.
... x² = 30
... x² - 30 = 0
... (x -√30)(x +√30) = 0
By the zero product rule, the solutions are values of x that make a factor be zero.
... x - √30 = 0 . . . . the first factor is zero
... x = √30
... x + √30 = 0 . . . . the second factor is zero
... x = -√30
The solutions are . . .
... x = ±√30 . . . . . matches your 3rd choice
You can set up a ratio of side lengths as follows:

Now we just solve for x (by cross-multiplying):


So,
x = 75 units.
Multiply 62 by 3 and you get 186
