Answer 1

80 degrees i believe

Explanation:

if supplementary angles =180 then 180-100=80

Answer 2

m∠QRS = 80°

Explanation:

We know that, sum of supplementary angles is 180°.

Given that ∠ABC and ∠QRS are supplementary, and m∠ABC = 100°.

So, m∠ABC + m∠QRS = 180°

=> 100° + m∠QRS = 180°

=> m∠QRS = 180° - 100°

=> m∠QRS = 80°
