a line is 180 degrees. also, all angles in any triangle add up to 180 degrees. so, find the missing angle in the triangle by 180-30-25=125 degrees. Then to find angle 4, 180-125=55 degrees.

Answer: $\frac{1}{9}$

Step-by-step explanation:

When any number has a negative exponent, all the negative exponent is doing is flipping the sides.

When we plug -3 in for x we get $-3^{-2}$ .

Now just imagine the -3 in fraction form as $\frac{-3}{1}$ . And all you do now is just flip the sides to get $(\frac{1}{-3} )^{2}$

And now apply the exponent 2 to the 1 and negative 3.

1 to the power of 2 is just 1

-3 to the power of 2 is 9.

So your answer is $\frac{1}{9}$
