A triangles angles measure up to 180° so before finding x you must find the missing angle.

So lets make an equation:

180=22+23+a

(a is the missing angle)

So add 22+23=45

180=45+a

Subtract 45 from both sides to isolate A

180-45=45-45+a

135=a

135° is your missing angle

So now we have to find X

A straight line measures to 180° so now we subtract 135°(or a) from 180°

180-135=x

x=45

Therefore X is 45°

Given that 310 = 59 049 , what is 3-10 expressed as an exact value?

Advocard [28]

$x^{-n}=\frac{1}{x^n} \\ \\
3^{10}=59049 \\
3^{-10}=\frac{1}{3^{10}}=\frac{1}{59049} \\ \\
\boxed{3^{-10}=\frac{1}{59049}}$
