Question 1 Report

TQ is tangent to circle XYTR, \( \angle YXT = 32^\circ \), \( \angle RTQ = 40^\circ \). Find \( \angle YTR \)

Answer Details
< TWR = < QTR = 40 ∘  (alternate segment)

< TWR = < TXR = 40 ∘ (Angles in the same segments)

< YXR = 40 ∘  + 32 ∘  = 72 ∘

< YXR + < YTR = 180 ∘ (Supplementary)

72 ∘  + < YTR = 180 ∘

< YTR = 180 ∘  - 72 ∘

= 108
