Question

do the sum in proper method​

Answer 1

Step-by-step explanation:

in ∆PQR,

QRS is an external angel so

QRS= QPR+PQR

QRS = 35+30

QRS = 65 = TRS

In ∆TRS,

QTS is an external angle so

QTS= TRS +TSR

x= 65+30

x= 95

#666

Answer 2

Answer:

x = 95°

Step-by-step explanation:

In ∆PQR,

<TRS = <PQR + <QPR = 30° + 35° = 65°

(ext. angle is equal to the sum of two int. opposite angles)

In ∆RST,

<QTS = <TRS + <TSR = 65° + 30° = 95°

(ext. angle is equal to the sum of two int. opposite angles)

And <QTS = x = 95°
