Question

17. ABC is congruent to PQR and A = 60° and B=70° then what is the measure of R?​

Answer 1

Answer:

here

ABC congruent PQR

therefore

A=P,B=Q,C=R

A=50°,Q=60°

measure of triangle is 180°

P+Q+R=180

50+60+R=180

110+R=180

R=180-110

R=70°

this prove

ABC congruent to PQR

therefore,

angle A = angle P = 50 degrees

angle B = angle Q = 60 degrees

angel C = angle R = 70 degrees

A + B + C = 180

50 + 60 + C = 180

110 + C = 180

C = 70

by angle sum property of .

hence angle R = 70 degrees

Answer 2

Plz mark as brainiest answer.

∆ABC=∆PQR.

ANGLE A =ANGLE P = 60

ANGLE B = ANGLE Q =70

WE KNOW THAT:-

SUM OF TRIANGLE IS 180 DEGREE.

70+60+X=180

X=50

≈ANGLE R= ANGLE C =50 DEGREE.

THEREFORE,R=50 DEGREE.
