Answer:
sorry I didn't know...........................
Okay, so you take the length of your hypotenuse (17) and plug it into the pythagorean theorem as C. And then plug the given side (15) into A or B (doesn't matter which). So:
<span><span>a2</span>+<span>152</span>=<span>172</span></span>
<span><span>a2</span>+225=289</span>
Now isolate a^2 by subtracting 225 from both sides of the equation.
<span><span>a2</span>=64</span><span>
Find the square root of both sides to find the missing value.
a = 8</span>
