Question

1) In ∆PQR, ∠ P = 50

, ∠ Q = 45

, find measures of, ∠ R.​

Answer 1

Step-by-step explanation:

using angle sum property of a triangle

<p +<q + <r = 180

50 + 45 +<r = 180

95 + <r = 180

<r = 180 - 95

<r = 85

Answer 2

Answer:

Angle P + Angle Q + Angle R = 180° ( sum of measures of all angles of a Triangle is 180° )

50° + 45° + Angle R = 180°

95° + Angle R = 180°

Angle R = 180° - 95°

Angle R = 85°
