Answer:
63
Step-by-step explanation:
All the angles inside the triangle must = 180
So 180 - 62 - (angle1) = ?
Angle 1 is { 180 - 125 = 55}
180 - 62 - 55 = 63
Use the quadratic formula to solve. the answer is the third one down
x= -sqrt10 - 4 and sqrt10 - 4
or in their notation above x= -4+/-10--sqrt
