Answer:
2 *( 3+7-9) =(1+5) - ( 8 -4 )
Step-by-step explanation:
2 _( 3_7_9) = (1_ 5) _ ( 8 _4 )
I just started playing with things
2 *( 3+7-9) = (1_5 ) _ ( 8 _4 )
2 * (10-9)
2*1
So the left side is 2
Now to make the right side 2
(1+5) - ( 8 -4 )
6 - 4
2
Set them equal to each other and solve
3x + 39 = 4x +34
-x=-5
X=5
Plug it in
3(5) + 39 = 54
4(5) +34 = 54
For the final angle ,
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72
A) 3(a - b) = 3*a +3*-b = 3a - 3b EQUAL
b) 2a(2 + b) = 4a + 2ab NOT EQUAL
