A parallelogram has one angle thatmeasures 76°. The measures of the other three angles in the parallelogram are 76°, 104°, and 104°.
That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
A parallelogram has one angle that measures 76°.
We already know that in a parallelogram opposite angles are equal.
1st angle = 76°
Third angle = 76°
And let the other 2nd and 4th angles be x and x
So, The sum of all the angles of quadrilateral
76° + 76° + x + x = 360°
152° + 2x = 360°
2x = 360° - 152°
2x = 208°
Therefore x = 104°
Hence, We have got all angles that are 76°, 76°, 104°, and 104°.

Step-by-step explanation:
We know that in a parallelogram opposite angles are equal so
1st angle = 76°
Third angle = 76°
And let the other 2nd and 4th angles be x and x
Now
76° + 76° + x + x = 360° <being sum of angles of quadrilateral >
152° + 2x = 360°
2x = 360° - 152°
2x = 208°
Therefore x = 104°
We have got all angles
76° , 76° , 104° and 104°
it is true!!!! hope this helps
5+3x=7(x+3)
Answer:
-4
Step-by-step explanation:
Simplifying
5 + 3x = 7(x + 3)
Reorder the terms:
5 + 3x = 7(3 + x)
5 + 3x = (3 * 7 + x * 7)
5 + 3x = (21 + 7x)
Solving
5 + 3x = 21 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
5 + 3x + -7x = 21 + 7x + -7x
Combine like terms: 3x + -7x = -4x
5 + -4x = 21 + 7x + -7x
Combine like terms: 7x + -7x = 0
5 + -4x = 21 + 0
5 + -4x = 21
Add '-5' to each side of the equation.
5 + -5 + -4x = 21 + -5
Combine like terms: 5 + -5 = 0
0 + -4x = 21 + -5
-4x = 21 + -5
Combine like terms: 21 + -5 = 16
-4x = 16
Divide each side by '-4'.
x = -4
Simplifying
x = -4
