transverse s at angle 135°
180° - 135° = 45°
Angle 2 is congruent to 45° because they're alternate exterior angles.
transverse t at angle 120°
180° - 120° = 60°
Angle 3 is congruent to 60° because they're alternate exterior angles.
One rule for exterior angles in triangles is that the exterior angle is equal to the sum of the two angles adjacent to the opposite angle of the exterior angle.
135° = angle 1 + 60°
angle 1 = 75°
120° = angle 1 + 45°
angle 1 = 75°
Therefore angle 1 is 75°,angle 2 is 45° and angle 3 is 60°
Step-by-step explanation:

Totally false. Just take your picture and either rotate the radius just a little,
or rotate the chord just a little. The radius will still intersect the chord, but
it won't bisect it.
Could it be possible that you might possibly have mis-copied the question.
If you said that the radius intersects the chord and is perpendicular to it,
then the statement would be true. Could that be the reason that the little
'corner' is marked in on the drawing ... to show that they're perpendicular ?
The three angles create a triangle. The sum of the angles of a triangle is always 180°.
Solving for x,
45° + 35° + x = 180°
x = 100°
