Answer:
x = 13, y = 26, z = 5
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
2x + 110 + 44 = 180
2x + 154 = 180 ( subtract 154 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
------------------------
2x and y are alternate angles and congruent , so
y = 2x = 2(13) = 26
--------------------------------
The opposite sides of a parallelogram are equal
3z - 1 = 14 ( add 1 to both sides )
3z = 15 ( divide both sides by 3 )
z = 5
Answer:
11m+n
Step-by-step explanation:
the 2 equations are vertical angles, which mean they are equal to each other.
Set them to equal and solve for X:
x+40 = 3x
Subtract 1x from each side:
40 = 2X
Divide both sides by 2:
X = 40/2
X = 20
X = -1/4
Move the 1 to the other side then divide by 4 on both sides
