Answer: √28

Solution:
The three squares form a triangle where the hypotenuse is 8 and the right side is divided into 6 and a.

So 8^2 = 6^2 + a^2
(Using the Pythagorean theorem)

64 = 36 + a^2
64 - 36 = a^2
28 = a^2
a = √28

Write the expression as the sine or cosine of an angle sin(pi/7) cos(x) + cos(pi/7) sin(x)
Natasha_Volkova [10]

Answer:

\sin(\frac{\pi}{7}+x)

Step-by-step explanation:

We are going to use the identity

\sin(a+b)=\sin(a)\cos(b)+\cos(a)\sin(b)

because this identities right hand side matches your expression where

a=\frac{\pi}{7} and b=x.

So we have that \sin(\frac{\pi}{7})\cos(x)+\cos(\frac{\pi}{7})\sin(x) is equal to \sin(\frac{\pi}{7}+x).
