Question

please give me answer with explanation fast​

Answer 1

Answer:

2.60°.

Step-by-step explanation:

<PQR= 110°

<RST= 130°.

<QRS=?

linear pair of <PQR= 180°-110° = 70°.

linear pair of <RST = 180°-130°= 50°.

Now,let's form a TRIANGLE QRS.

Triangle QRS = 70°+50°+x = 180°

120°+x= 180°

x= 180°-120°

= 60°.

<QRS = 60°.
