WebAnglei = 53° because of the alternate segment theorem. Anglej = 53° because it is the alternate angle to 53°. Anglek = 180° − 53° − 53° = 74° as angles in a triangle total 180°. 1 The angle between a tangent and chord is equal to the angle in the alternate segment. 2 As there are two parallel lines, angle 53° is equal to anglej ... WebThe angle in a semicircle is 90°. y = 90°. Angles in a triangle add up to 180°. \ [z = 180 - 30 - 90 = 60^\circ\] Using the alternate segment theorem: angle \ (x = z\) \ [x = 60^\circ\] 1. 2.
