X= 5
To find the side a we will use the Pythagorean Theorem:
<span><span>a2</span>+<span>b2</span>=<span>c2</span></span>
After substituting <span>b=12</span> and <span>c=13</span> we have:
<span><span>a2</span>+<span>122</span>=<span>132</span></span><span><span>a2</span>=<span>132</span>−<span>122</span></span><span><span>a2</span>=169−144</span><span><span>a2</span>=25</span><span><span>a=5</span></span>
Its D or B because it talks about how low its gonna be or higher :P
