Answer:
∠AB=9
Step-by-step explanation:
<em>the pyagrothyes therom= </em>
<em>+</em>
<em>=</em>![c^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D)
<em>to find ∠AB we need to find the height of the triangle.</em>
<em>replace the variables:</em>
<em>+</em>
<em>=</em>![9^{2}](https://tex.z-dn.net/?f=9%5E%7B2%7D)
<em>=</em>
<em>-</em>
<em>=</em>![a^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D)
<em>simplify:</em>
<em>81-36=</em>![\sqrt{45}](https://tex.z-dn.net/?f=%5Csqrt%7B45%7D)
<em>now we solve for ∠AB</em>
<em>replace the variables:</em>
<em>+</em>
<em>=</em>![c^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D)
<em>simplify:</em>
<em>36+45=</em>![\sqrt{81}](https://tex.z-dn.net/?f=%5Csqrt%7B81%7D)
<em>=9</em>
I hope this helps you!!
have a nice day!!
