Question

The angles of a triangle are (3x-6°),(5x+25)°and (6x+20°). find measure of the angels.​

Answer 1

Step-by-step explanation:

$(3x - 5) +(5x + 25) + (6x + 20) = 180 \\ 3x + 5x + 6x + 40 = 180 \\ 14x = 180 - 40 \\ 14x = 140 \\ x = 140 \div 14 \\ x = 10\\ so \: each \: angle \: is \: 30 - 5 = 25 \\ 50 + 25 = 75 \\ 60 + 20 = 80$
