All the others are 90 degrees too
Step-by-step explanation:
In a parallelogram opposite angles are congruent. Also in a quadrilateral the sum of angles is 360 degrees. since their are two pairs of congruent angles you could make an equation and it would look like this: 180+2x =360. x would be 90 making every angle 90 degrees.

Answer:
probably 4.5 if im not mistaking
Answer:
The standard form of
is -2 x + 3 y = 21.
Step-by-step explanation:
Here, the given expression is : y= 2/3 x +7
The standard form of the equation is ax + by = c
Now, simplifying the above expression:

or, 
or, -2x + 3y = 21
Hence, the standard form of
is -2x + 3y = 21.
Answer:
1. Subtract 2 from both sides.
2. Multiply both sides by 2.
3. Take the square root of both sides.
4. Subtract 5 from both sides.
