step-by-step explanation:
|ab| = 1.4 = 4
h = 1.4 = 4
a(abc) area = 4.4 = 16/2 = 8
area of abc = 8 cm^2
good luck ! ; )
h= 12 inches
x = 2
if sr parallel to ba then the sides bc and ac are in proportion, that is
= ← substitute values
= ( cross- multiply )
27x = 6(4x + 1)
27x = 24x + 6 ( subtract 24x from both sides )
3x = 6 ( divide both sides by 3 )
