Answer: OPTION A.

Step-by-step explanation:

Since the sum of the interior angles of a quadrilateral is 360 degrees.

We can write the following expression:

$m\angle C+m\angle BED+m\angle CBE+m\angle D=360\°$

We know that ABEF≅CBED. Then:

$m\angle A=m\angle C\\\\m\angle F=m\angle D$

Substituting and solving for $m\angle A$ , we get:

$m\angle A+82\°+152\°+98\°=360\°\\\\m\angle A=360\°-82\°-152\°-98\°\\\\m\angle A=28\°$

What is the slope of the linear equation 4x - 5y = -30

MariettaO [177]

Answer:

The slope of the line 4x – 5y = 12 is m = 4/5.

Step-by-step explanation:

To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.
