Answer:

Explanation:

This is a basic right angle problem relating to Pythagoras theorem as one approach.

we know.


a^2+b^2=y^2

(letting the hypotenuse of the left triangle as y)

then,


7^2+8^2=y^2\\y=√(113)(neglecting negative root)

now since you know the value of y use the same formula to find the value of x. Keep in mind the identification of opposite , adjacent and hypotenuse sides.
