Question

12. If two straight lines intersect each other in such a way that one of the angles so formed measure
90°, then each of the remaining angles measures is
(a) 50° (b) 75° c) 90° (d) 60°​

Answer 1

Answer:

90

Step-by-step explanation:

if two lines intersect each other at 90 it means, they are perpendicular to each other.

if one angle is 90, then it's supplementary angle is also 90 and likewise all angles will end being 90

Answer 2

Answer:

90°

Step-by-step explanation:

If two straight lines intersect each other in such a way that one of the angles so formed measure 90° then each of the remaining angles measures is 90°
