yes
Answer:
The marked angle GEF is 25
Step-by-step explanation:
Here, we want to calculate the value of the marked angle
Mathematically, a diagram should do justice to this
Please check the attachment for the diagram
The theorem we want to use is that the sum of opposite interior angles equals the exterior angle
Thus, mathematically;
2x + 1 + x + 19 = 6x + 2
3x + 20 = 6x + 2
6x-3x = 20-2
3x = 18
x = 18/3
x = 6
The angle marked GEF is x + 19
That will be 6 + 19 = 25
Answer:
1 is comutative 2 is distributive 3 is addition and 4 is multiplication
x+142 =3x+64
subtract x from each side
142 = 2x+64
subtract 64 from each side
142-64 = 2x
78=2x
divide by 2
78/2 = x
x=39
The number is 39
Answer:
it is this one
Step-by-step explanation:
because since x is 4 and y is 8 that one matches up better than any other one
