Step-by-step explanation:
z+z+z
-4+-4+-4
-8+-4
-12
The answer is -9 and 4.
-9×4 = -36.
-9+4 =-5
Set The Numbers On The Side Equal To The Equation. Use Inverse Operation And Divide Since The X Is Used In Multiplication.
The 3 inside angles need to equal 180.
Subtract E from 180 to find the sum of the other two angles:
180 - 104 = 76
Now because EF ≅ DE , angle D and F would be the same so divide 76 by 2
Angle D = 38
