Question

Solve for x..
a) x= 8
B) x= 22.5
C) x= 32.4
D) x= 40.5

Answer 1

x/18 = (15+12)/12 <=== when you put in fractions, the numerator or denominator from both the fractions should be from the same triangle

x/18 = 27/12 <=== cross multiply it
12x = 27×18
x = 486/12
x = 40.5

Answer 2

12/27= 18/x
so
x = 15*18 / 12
x = 270/12
x = 40.5

answer
D . x = 40.5
