In △ABD and △ACD, we have
DB=DC ∣ Given
∠ADB=∠ADC ∣ since AD⊥BC
AD=AD ∣ Common
∴ by SAS criterion of congruence, we have.
△ABD≅△ACD
⇒AB=AC ∣ Since corresponding parts of congruent triangles are equal
Hence, △ ABC is isosceles.

<span>multiply both sides of the bottom by 4 and add </span><span> 5x+8y=-29 </span>
<span> 28x-8y=268</span>
33x=-297
<span> x=-9 </span>
<span>5(-9) +8y= -29 </span>
