Question

find the unknowns in the following​

Answer 1

Answer:

sum of both angles will be answer of your question

Answer 2

Answer:

x = 20° , y = 50°

Step-by-step explanation:

We know that the sum of adjacent angles is $180$°

So, ∠E + ∠S = 180°

(3x-10°) + (5x+30°) = 180°

8x + 20° = 180°

8x = 160°

x = 20°

∴ ∠E = (3(20) - 10)

       = 50°

∠S = 5(20) + 30

     = 130°

y = ∠E [∵Opposite angles in a IIgm are equal]

y = 50°
