Answer 1

Answer:

∠SLR = 50°

Step-by-step explanation:

from the given figure,

SR || MN   and if LM is taken as transversal,

then ∠LRS = ∠RMN = 45°     (∵ corresponding angles )  -------------- (1)

also ∠LSR & ∠NSR are linear pair

=> ∠LSR + ∠NSR = 180°

=> ∠LSR + 95° = 180°

=> ∠LSR = 180° -  95° = 85°    ------------------------------ (2)

now , taken the ΔSLR, we know

∠SLR + ∠LSR + ∠SRL = 180°   (sum of all angles in a triangle is 180°)

=> ∠SLR +85° +45° = 180°        , from (1) & (2)

=> ∠SLR = 180° -130°

=> ∠SLR = 50°

Answer 2

Answer:

ok

Step-by-step explanation:

In the figure , NLM is a triangle . We have to find out the measurements of one of the side of the triangle which is SLR.

We know , total meSurement of a triangle is 180 degree

now angle m equals the measurement of angle l .So the angle SRL EQUALS TO =(180-130)

=50 degree
