I'm trying to help my daughter and have a question. The zeros in my question should be theta

in a right-angled triangle, one of the angles 0 has tan 0 = 1. the length of the hypotenuse is 10cm. what is the area of the triangle?

tan^-1(1) = 45 = 0

As tan = opposite side/adjacent side and tan(0) = 1, the opposite and adjacent side must be equal in length (a number divided by itself is always equal to 1).

From here you should be able to use Pythagoras theorem to calculate the opposite and adjacent side as you know they are both equal and then be able to work out the area of the triangle.
