Answer:
use Pythagoras theorem
Step-by-step explanation:
- get the opposite square it plus the adjacent side square it also should be equal to the hypotune squared also
- x² + (X +17)²= 25² expand (X+17)²
- x² + x² + 17² + 34x = 625
- 2x² + 34x + 289 = 625 get 625 minus 289
- 2x² + 34 x = 336 divide through by 2
- X²+ 17 X = 168
- solve the quadratic equation using any method
- if I use bulldozer method
- a=1 b=17 c=-168
- put in that quadratic formula
x=7 or X=-24 but for second value of X is not correct since you can not have a negative length for opposite side
therefore take X=7 as the answer
