Answer:

Step-by-step explanation:
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so

substitute the given values

solve for x


Find the angle measurements



Write out the sum formula for sin
<span>sin(x + y) = sinxcos + sinycosx </span>
<span>Then expand sin(a + b) + sin(a - b) </span>
<span>sinacosb + sinbcosa + sinacosb - sinbcosa </span>
<span>The 2nd and 4th terms cancel and you get </span>
<span>2sinacosb</span>
