Only two triangles:
The 90* angle is stable, so you can change only the position of the 50* and 40* angles.
1 triangle: 40* is right to the 90*
2 triangle: 40* is left to the 90*
Hope this helped you!
Answer:
Step-by-step explanation:
-15d - 12 = -4(d + 3) - 11d
-15d - 12 = -4d - 12 - 11d
-15d - 12 = -15d - 12
+12 +12
--------------------------------------------
-15d = -15d
---------------------------------------------
All real numbers are the solution.
IQR means middle or in this case it is 2
