In a parallelogram, opposite sides have the same length.
3x + 9 = 5x -5
group like terms on one side
9 + 5 = 5x -3x
14 = 2x
x is 7.
Since AB is 5x -5
AB = 5(7) -5
AB = 30.
BX is half of the line DB. So BX = DX
5y = 7y - 10
10 = 7y -5y
10 = 2y
y =5.
Since BX = 7y - 10
BX = 7(5) -10
BX = 25
Answer:
Look at the explanation :)
Step-by-step explanation:
Angle 2 and 3 are supplementary angles, which means they are equal.
Therefore, if
Angle 2 = 4x - 26
and
Angles 3 = 3x + 4,
It means that 4x - 26 = 3x + 4
Solve it,
4x = 3x + 30
x = 30
Input x to each angles,
Angle 2,
4(30) - 26 = 120 - 26 = 94
Angle 3,
3(30) + 4 = 90 + 4 = 94
Hope this helps :)
Let me know if there are any mistakes!!
The answer is C.
Note when Soro divides both sides by -2.5 to solve the equation. When multiplying/dividing by a negative number, one should always reverse the inequality sign, but Soro forgot to do this.
-2.5x≥-30
After this step, the answer SHOULD HAVE been:
x≤12
Let me know if you need any clarifications, thanks!
One specific triangle CAN be made with those angles because of the 180 degree total.
