Question

Find the all three angles of a triangle​

Answer 1

Answer:

$(x + 25) + (4x - 15) + (2x - 10) = 180 \\ 7x + 50 = 180 \\ 7x = 180 - 50 \\ 7x = 130 \\ x = \frac{130}{7} \\ x = 18 \\ a = x + 25 \\ a = 18 + 25 \\ a = 43 \\ b = 2x - 10 \\ b = 2 \times 18 - 10 \\ b = 36 - 10 = 26 \\ c = 4x - 15 \\ c = 4 \times 18 - 15 \\ c = 72 - 15 = 57$
