Answer 2

Answer:

x = 20. ∠B = 92° and ∠C = 40°

Step-by-step explanation:

Angles of a triangle are ∠A = 48°, ∠B = (6x - 28)° and ∠C = (2x)°

Since sum of all the angles of the triangle is 180°

So ∠A + ∠B + ∠C = 180°

48° + (6x - 28)° + (2x)° = 180°

48 + 6x - 28 + 2x = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = $\frac{160}{8}=20$

Now ∠B = (6x - 28) = 6×20 - 28

∠B = 120 - 28 = 92°

And ∠C = 2x° = 2×20 = 40°

Therefore, x = 20. ∠B = 92° and ∠C = 40° is the answer.
