Question

Please answer me the correct one with method ok please ​

Answer 1

Answer:

60

Step-by-step explanation:

because angle sum property of triangle is 180

so addition of 55+65 is 120 and if we subtract 180-120 then it will be 60.

Answer 2

Answer:

∠A  = 60

Step-by-step explanation:

Using angle sum property:

sum of all angles of a triangle = 180°

=>  ∠A + ∠B + ∠C = 180°

=> ∠A + 55 + 65 = 180°

∠A + 120° = 180°

∠A = 180 -120

∠A = 60°
