The other angle would be 35 degrees. This is because in a straight line (the wood) there are 180 degrees and when you take away 145 (the cut) you are left with 35.

180-145= 35

I hope this helps!

Answer:

Step-by-step explanation:

Square roots have a neat property: $\sqrt{ab}=\sqrt{a}\sqrt{b}$ provided a and b are positive real numbers.

This property is what's behind simplifying square roots. You look for perfect square factors (4, 9, 16, 25, 36, ...) inside the square root sign.

Example: $\sqrt{20}=\sqrt{4\times5}=\sqrt{4}\sqrt{5}=2\sqrt{5}$ .

In this problem, both factors are perfect squares.

$\sqrt{9\times144}=\sqrt{9}\sqrt{144}=3\times12=36$
