Question

Observe the figure, and find the measures of ∠PRS and ∠RTS.

Answer 1

Answer:

Step-by-step explanation:

• ∠PRS=∠PQR+∠RTS  (∵external angle =sum of 2 internal angles opposite to it)
• ∴∠PRS=40+30=70

  ∠RST+∠TRS+∠STR=180(∵Angle sum property in a triangle)

∠RTS+20+70=180

∠RTS=180-90=90
