Question

if triangle ABC~triangle PQR, and angle A+angle B=115 then find angle R​

Answer 1

Answer:

angle r =65 degree

Step-by-step explanation:

since abc is congruent to pqr

angle a = angle p

angle b = angle q

angle c =angle r

angle a +angle b =115  degree

angle c = 180 degree - 115 degree = 65 degree(asp)

anglec = angle r = 65 degree

Answer 2

∆ABC ≈ ∆PQR [Given]

angle A = angle P

angle B = angle Q

angle C = angle R

angle A+angle B = 115° [Given]

angle C = 180°–115°

=> 65°

angle C = angle R = 65°

angle R = 65° Ans.
