MaRussiya [10]

Answer:

x = 2 $\sqrt{5}$

Step-by-step explanation:

'x' can represent the hypotenuse of a right triangle with a base of 4 (11-7) and a height of 2

use Pythagorean Theorem to find 'x':

2² + 4² = x²

4 + 16 = x²

x² = 20

x = $\sqrt{20}$

x = $\sqrt{4}$ · $\sqrt{5}$

x = 2 $\sqrt{5}$

If cos x = −6/7, and 90° < x < 180°, what is cos⁡(2x)?

Naddik [55]

Recall the double angle identity:

$\cos2x=\cos^2x-\sin^2x=2\cos^2x-1$

Then

$\cos2x=2\left(-\dfrac67\right)^2-1=\dfrac{23}{49}$
