Question

please show me the process ​

Answer 1

Step-by-step explanation:

IN ∆ ABC

angle A = 180- ( angle B + angle C )

= 180 - ( 60 + 50)

=. 180 - ( 110)

=. 180 - 110

= 70°

so angle A = 70°

IN ∆ ABC AND ∆ PQR

angle C= angle R (each 50)

angle B = angle P ( each 60 ° )

AB = QR ( GIVEN)

so, by. AAS congruency criterion ∆ABC is congruent to ∆ QPR
