Question from Taylor: how do i find the height of a triangle with a base of 3 and a side of 5 the book says 4 but i cant get that |
Hi Taylor,
Is one of the angles a right angle? If so then Pythagoras theorem can help. It says that if the hypotenuse (the side opposite the right angle) has length c units and the other two sides have lengths a and b units then
a2 + b2 = c2.
You know two of a, b and c so substitute the values into the equation above and solve for the remaining variable.
