Question

given ΔABC~ΔDEF,if angle A is 45 degree and angle E is 35 degree than angle B=?​

Answer 1

Answer:

∠B 35° and ∠C = 100°

Step-by-step explanation:

As ΔABC ≅ ΔDEF,

∠A = ∠D

∠C = ∠F

And ∠B = ∠E

So as ∠B = ∠E and ∠E = 35°

∴ ∠B = 35°

Now i think you miswrote the question and have asked for C°, here's the answer -

We know that the sum of all interior angles of a triangle = 180°

So ∴ we know from the above explanation that -

∠A = 45°   [given in question]

∠B = 35°   [as explained above]

So ∴ ∠C = 180 - ∠A + ∠B

= 180 - 45 + 35

= 180 - 80

= 100°

Therefore ∠C = 100°

And As ∠C = 100°, ∠F = 100°
