<u>It comprises of two parts: </u>
<u>Using Pythagorean theorem, lets find the value of x:</u>
- x² + 15² = 17²
- x² = 289 - 225
- x² = 64
- x = 8 m
<u>Same rule for y:</u>

- y² = 289 - 64
- y² = 225
- y = 15 m
<u>The width of the street (road) is:</u>
73%. Do 30-8 to find the number of correct answers. That’s 22 so now divide it by 30 to find the percentage. 22/30 is equal to 0.73 or 73%
