1/169=1/3 what's the exponent? how do i figure it out?

Step-by-step explanation:

We have been given an equation . We are asked to write the missing exponent for our given equation.

We can see that 169 is square of 13, so we can write left side of our equation as:

We can raise 1 to any power and answer will be same.

Raising 1 to 2nd power, we will get:

Since both numerator and denominator is raised to 2nd power, so we can raise  to 2nd power as:

Therefore, our missing exponent is 2.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
