<h3><u>Answer:</u></h3>
  • x = 66°
  • y = 48°
<h3><u>Step-by-step explanation:</u></h3>

<u>Since this is an isosceles triangle, the base angles must be the same. Hence, </u><u>x = 66°.</u>

<u>Since we have found x, we can find y by using the 180-angle method.</u>

  • => y + 66 + 66 = 180
  • => y + 132 = 180
  • => y = 180 - 132
  • => y = 48°
<h3><u>Conclusion:</u></h3>

Therefore, the answers are:

  • x = 66°
  • y = 48°

Hoped this helped.
