Question

Answer the following
​

Answer 1

Answer:

70 degrees

Step-by-step explanation:

Since YOUR is a Parallelogram, we can write

$\angle OYR = \angle RUO = 120 ^ \circ$

Now, we know that exterior angle equal sum of interior angles in a triangle. So,

$\angle RSY+\angle SRY=\angle RYO\\\rightarrow \angle RSY = 70^\circ$
