Answer:

x = 13.5

Step-by-step explanation:

To find x, we use the sine rule

For the sine rule,

the ratio of the sides to the sine of the angle facing the side is equal for all the sides of the triangle

Thus,

x/sin 34 = 11/ sin 27

x = 11 sin 34/sin 27

x = 13.5

Answer:

$a \: \: x = \frac{ -1 ± i\sqrt{139}}{14}$

Explanation:

Since this is unfactorable, use the Quadratic Formula:

$x = -b ± \frac{ \sqrt{ {b}^{2} - 4ac}}{2a}$

Now, take the information and input it:

$-1 ± \frac{ \sqrt{1 - 4(7)(5)}}{2(7)} \\ \\ -1 ± \frac{ \sqrt{ -139}}{ 14} = \frac{-1 ± i\sqrt{139}}{14}$

I am joyous to assist you anytime.
