Answer:
x=31°
Step-by-step explanation:
Ok,
We know the sum of the angles in a triangle add up to 180°.
So,
2x+63+(2x-7)=180
2x+63+2x-7=180
Add like terms
4x+56=180
4x=124
x=31°
Hope this helps!
Answer:
y = 36
Step-by-step explanation:
The two angles are supplementary since they are same side exterior angles
74 + (2y+34) = 180
Combine like terms
2t+108 =180
Subtract 108 from each side
2y = 180-108
2y = 72
Divide by 2
2y/2 = 72/2
y =36
Answer:
Step-by-step explanation:
4 : 2
8 : 4
12 : 6
16:8
Assuming that you meant 4(x^2*y^4)^3
the answer would be 108 x^6 y^12
Answer:
If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
