4x +28 and 68 are vertical angles and are equal.
Set them to equal each other to solve for x:
4x +28 = 68
Subtract 28 from each side:
4x = 40
Divide both sides by 4:
x = 40/4
x = 10
Remember the notation..
When you have a triangle called ABD, the angles may be called in theses equivalent ways>
angle A is equivalent to ∠ DAB
angle B is equivalent to ∠ ABD
angle D is equivalen to ∠ BDA
Then given that the two triangles are congruent, you can say an
angle B = angle F = ∠ EFC
So the answer is the last option of the list.
The answer is 5x-59
To get this answer you have to follow pemdas and remember you can’t add variables to non variables, so you just expand the equation
As an example
5x + 6 -2x +7
You would get
13-3x
