Answer:

x = 3\sqrt{3}

Step-by-step explanation:

Let's use the Pythagorean theorem

x^{2}  + 9^{2}  =  (2x)^{2} \\x^{2}  + 81 = 4x^{2} \\3x^{2}  = 81\\x^{2}  = 27\\x = \sqrt{27}  =  3\sqrt{3}

Find the function value of cos^2 (7pi/8)
Kamila [148]
\cos^2\dfrac{7\pi}8=\dfrac12\left(1+\cos\dfrac{7\pi}4\right)
=\dfrac12+\dfrac12\cos\left(-\dfrac\pi4\right)
=\dfrac12+\dfrac12\cos\dfrac\pi4
=\dfrac12+\dfrac1{2\sqrt2}
=\dfrac{\sqrt2+1}{2\sqrt2}
=\dfrac{2+\sqrt2}4
