The sum of the measures of ∠QRT and ∠TRS is 180∘. What is the measure of ∠TRS If ∠TRS = ∠QRT?​

Sagot :

Let the angles be x

  • ∠QRT = x
  • ∠TRS = x

We are taking both angles as x because they are equal!

[tex] \mathcal{∠QRT + ∠TRS = 180 \degree}[/tex]

[tex] \tt \: x + x = 180 \degree[/tex]

[tex] \tt \: 2x = 180 \degree[/tex]

[tex] \tt \: x = 90 \degree[/tex]

Thus, The measure of both angles is 90°...~
