If DBbisects ZADC, m_1 = (3x + 4)', and m2 = (5x –2)º, find 'x'.

x = 2

step-by-step explanation:

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 )

x = 2

55 degrees because 55+55=110 degrees

the answer is  

c.

90.0π cm^2

hope you got it.
