Question

If∆ABC≅∆PQR,∠Q=60⁰,∠R=40⁰ then ∠A is how much?​

Answer 1

Answer:

If∆ABC≅∆PQR,∠Q=60⁰,∠R=40⁰ then ∠A is how much?

∠ A = 40°

because ∠R=∠A =40°

Answer 2

Answer:

∠A=180

Step-by-step explanation:

angle of triangle=180⁰

∠P+∠Q+∠R=∠A+∠B+∠C

∠A+∠60+∠40=∠A+∠60∠40=180

∠A+100=180

∠A=180 -100

∠A=80

∠
