You would do the opposite so literally just x 49.95 by 6.95 and 47.68 by 4.39 so the answers are 347 and 209 so website B
Answer:
x = 25
Step-by-step explanation:
The two angles form a straight line which is 180 degrees
2x+10 + 4x+20 = 180
Combine like terms
6x+30 = 180
Subtract 30 from each side
6x+30-30 = 180-30
6x = 150
Divide by 6
6x/6 = 150/6
x=25

Answer:
20 units (I used units because that's what i was taught when there isn't a specific unit)
Step-by-step explanation:
If the triangles are congruent, that means that everything is congruent/the same. So what we do is, we set both equations equal to each other.
6x - 3 = 4x + 9
And now we simplify.
6x - 3 = 4x + 9
-4x -4x
--------------------
2x - 3 = 9
+3 +3
-------------------
2x = 12
÷2 ÷2
---------------
x = 6
To find the perimeter, just multiply 6 by 4 since there's four sides. 6 x 4 = 20
