There are different ways to find the solution. (You can find solutions for this equation, but the solutions aren’t infinitely)
Examples
3•2+3•2=12
2+2=4
Or
3•0+3•4=12
0+4=4
Or
3•1+3•3=12
1+3=4

Answer:
x=2,BA=DA which is7
Step-by-step explanation:
5x-3=3x+1
both sides share an angle and B=D right angles
5x-3x=1+3
2x=4
x=4÷2
x=2
BA=5x-3
BA=5(2)-3
BA=10-3
BA=7
DA=3x+1
DA=3(2)+1
DA=6+1
DA=7
The answer is table B and graph A !!
Answer:
The exterior angle of 60° is 120°. The exterior angle of 65° is 115°. The exterior angle of 55° is 125°.
Step-by-step explanation:
The sum of the interior angle and the exterior angle is 180°. So you can subtract each interior angle from 180 and get the exterior angle.
180° - 60° = 120°
180° - 65° = 115°
180° - 55° = 125°
This is because you can imagine the lines of the triangle extending beyond the triangle. Then you can see where the other angles are. Hope this makes sense!
