Answer:
They are vertical angles
Step-by-step explanation:
They are congruent because they are across from each other over a straight line. They are also called vertical angles.
Answer:
30 seconds
Step-by-step explanation:
10x10=100 3x10=30
Answer:
Explanation:
-4y - 3x = -11 (1)
x - 2y = 17 (2)
x = 17 + 2y
Substitute x value in (1)
-4y - 3(17 + 2y) = -11
-4y - 51 - 6y = -11
-10y - 51 = -11
-10y = -11 + 51
-10y = 40
y = 40/-10
y = -4
Substitute the y value in (2)
x - 2(-4) = 17
x + 8 = 17
x = 17 - 8
x = 9
Therefore, x = 9 and y = -4
A square has equal sides. To find the area, you multiply the length and the height.
x*x=121
x^2=121
x=11
The length of each side is 11
A square has equal sides. To find the perimeter, you add all the sides together.
x+x+x+x=28
4x=28
x=7
The length of each side is 7
