Answer:

x = 4

Step-by-step explanation:

Given that DE is parallel to AC then DE divides the sides proportionally, so

$\frac{BD}{DA}$ = $\frac{BE}{EC}$ , substitute values

$\frac{x+2}{x}$ = $\frac{3}{2}$ ( cross- multiply )

3x = 2(x + 2) ← distribute

3x = 2x + 4 ( subtract 2x from both sides )

x = 4

Parallel lines x and w are cut by transversals z and y and form 4 angles at each intersection. Where line x intersects with line

ale4655 [162]

Answer:

$m\angle 1 =105^\circ\\m\angle 2 =75^\circ$

Step-by-step explanation:

The diagram is drawn and attached below.

From the diagram

$m\angle 2 =75^\circ $ (Alternate Angles)$

$m\angle 1+ m\angle 2 =180^\circ $ (Sum of angles on a straight line)\\m\angle 1+75^\circ =180^\circ\\m\angle 1 =180^\circ-75^\circ\\m\angle 1 =105^\circ$

What is the relationship between the lines with the following equations? 2x+8y=16 y=4x+7

dimulka [17.4K]

They are perpendicular because when you change 2x+8y=16 to slope intercept form it becomes y= -1/4x+2 and the slope (-1/4) is the negative reciprocal of 4, which is the slope for your other equation.
