Answer:

25. a = 60

26. a = 17

Step-by-step explanation:

In these two problems we are going to use a property of parallelograms that says: opposite angles have equal measure

so we have

25.

$6a+10=130\\\\6a=130-10\\\\6a=120\\\\a=60$

and for 26 we have

$4a-4=2a+30\\\\4a=2a+30+4\\\\4a=2a+34\\\\4a-2a=34\\\\2a=34\\\\a=17$

Lana71 [14]

Answer:

Step-by-step explanation:

A) Use the slope formula to find the slope m.

m=4/13

B) Use the point-slope formula, y−y1=m(x−x1) to find the equation of the line.

y=4/13x+198/13

C) Write in slope-intercept form, y=mx+b.

y=4/13x+198/13
