Remember that the sum of the sides of triangle is 180°.
First triangle :
x-1 + 4x + 2x + 2 = 180°
7x + 1 = 180°
7x = 180 - 1 = 179°
x = 179/7
x = 25.57 or 25.6 (rounding the decimal)
So, x - 1 = 25.6 - 1 = 24.6
4x = 25.6 × 4 = 102.4
2x + 2 = 25.6 × 2 + 2 = 53.2
Second Triangle :
They said ABC IS = DEF
So, DF = AB
DE = AC
FE = BC
Calculate and you will get answer
