Question

the angles of a triangle are:
a+b+c = 180°
a = x
b = x×⅓
c = x+26
find x.​

Answer 1

Answer:

x is equal to 26 is equal to 12 12

Answer 2

$x + \frac{x}{3} + x + 26 = 180 \\ \\ \frac{3x + x + 3x + 78}{3} = 180 \\ \\ 7x + 78 = 540 \\ 7x = 540 - 78 \\ 7x = 462 \\ x = \frac{462}{7} \\ x = 66$
