Answer: Answer Bellow

Step-by-step explanation:The sum of all four angles of the quadrilateral is 360°. To find the fourth angle or the missing angle in a quadrilateral when the measurements of three angles of a quadrilateral are known, then subtract the three angles from 360° to calculate the missing angle.

Help please will mark brainliest!!!
Daniel [21]

Answer:

45°

Step-by-step explanation:

Well, compared to 90°, it looks like it's just smaller, but not too small. It couldn't be 15° degrees, or 60°, as it was probably too much. I Don't think it's 30° either,  because it looked bigger than what a 30° angle would be.

Hope it helped!

In two or more complete sentences, describe how the substitution method works for solving a two-order system of equations.
padilas [110]
The first step is to set one equation equal to x or equal to y.
Ex. y = ..... or x = .....
The next step is to substitute that equation into the second equation in place of the x (or y), whichever you set it equal to.

Ex. x + y = 3
     2x + y = -1

y = -x + 3      2x + (-x + 3) = -1
                       x + 3 = -1
                       x = -4
y = -(-4) + 3    y = 7    (-4,7)
