Answer:
1. Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
2. Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Step-by-step explanation: give me brainly ;D
This is simple pythagoras, its just a²+b²=c². First you find the hypotenuse, which is 97; now you have the equation: x²+72²=97²
x²=9409-5184
x= √4225
x=65
the answer is 65m
