Answer:
x = 25

- Write out your equation: 55° = (x + 30)°
- Subtract 30 from each side, so it now looks like this: 25 = x
I hope this helps!
Let r = the distance from P(-2,-4) to Q(-4,-2);
<span>r = √{(-4 - -2)² + (-2 - -4)²} </span>
<span>r = √{-2² + 2²} </span>
<span>r = √{4 + 4} </span>
<span>r = √8 </span>
<span>Let q = the distance from P(-2,-4) to R(7,-1): </span>
<span>q = √{(7 - -2)² + (-1 - -4)²} </span>
<span>q = √{9² + 3²} </span>
<span>q = √{81 + 9} </span>
<span>q = √90 </span>
<span>Let p = the distance from Q(-4,-2) to R(7,-1): </span>
<span>p = √{(7 - -4)² + (-1 - -2)²} </span>
<span>p = √{11² + 1²} </span>
<span>p = √{121 + 1) </span>
<span>p = √122 </span>
<span>If PQR is a right triangle, then: </span>
<span>p² = q² + r² </span>
<span>122 = 90 + 8 </span>
<span>122 ≠ 98 </span>
<span>Therefore, it is not a right triangle.</span>
