Line PQ in the figure with
.
In the given figure, lines PQ || RS and line XY is their transversal. Rays AM and BM are the angle bisectors of ∠QAB and ∠ABS respectively. If m∠SBM = 52°, then what is m∠SBY?
. In the given figure, lines PQ || RS and line XY is their transversal. Rays AM and BM are the angle bisectors of ∠QAB and ∠ABS respectively. If m∠SBM = 52°, then what is m∠SBY?
a :
76°
b :
38°
c :
52°
d :
72°
Explanation :
The sum of the measures of angles in a linear pair is always 180°.∠ABS + ∠SBY = 180°104° + ∠SBY = 180°∠SBY = 180° - 104° = 76°
