What is the area of a triangle with the Base of √10 and a height of √13

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10
