Answer:
∠AB=9
Step-by-step explanation:
<em>the pyagrothyes therom= </em> <em>+</em>
<em>+</em> <em>=</em>
<em>=</em>
<em>to find ∠AB we need to find the height of the triangle.</em>
<em>replace the variables:</em>
 <em>+</em>
<em>+</em> <em>=</em>
<em>=</em>
<em>=</em> <em>-</em>
<em>-</em> <em>=</em>
<em>=</em>
<em>simplify:</em>
<em>81-36=</em>
<em>now we solve for ∠AB</em>
<em>replace the variables:</em>
 <em>+</em>
<em>+</em> <em>=</em>
<em>=</em>
<em>simplify:</em>
<em>36+45=</em>
 <em>=9</em>
<em>=9</em>
