Answer:
57 degrees
Step-by-step explanation:
Angle Ad is 123 and since it's on the same line it adds up to 180 180-123=57
The other angle would be 110 degrees. This is because a supplementary angle equals 180 degrees. So, 180-70=110<span />
first, you would rearrange the equation so that like terms were next to each other.
7y - 5y - x2 + 2x2 +3x - 17x
then you would reduce the equation based on like terms
2y + x2 - 14x
then simply rearrange the equation to get the answer, which is <u>B</u>
Answer:
The perimeter of the square is ![4\ in](https://tex.z-dn.net/?f=4%5C%20in)
Step-by-step explanation:
Let
x----> the length side of the square
we know that
In an isosceles right triangle the measures of the internal angles are 45°-90°-45°
so
the horizontal distance is equal to the vertical distance
![2=x+x](https://tex.z-dn.net/?f=2%3Dx%2Bx)
![x=1\ in](https://tex.z-dn.net/?f=x%3D1%5C%20in)
The perimeter of the square is
![P=4b](https://tex.z-dn.net/?f=P%3D4b)
we have
![b=1\ in](https://tex.z-dn.net/?f=b%3D1%5C%20in)
substitute
![P=4(1)=4\ in](https://tex.z-dn.net/?f=P%3D4%281%29%3D4%5C%20in)
