Answer: x = 11
Step-by-step explanation:
Complementary angles = 90*
Set the two equations equal to 90. Solve
4x + 6 + 4x - 4 = 90
8x +2 = 90
8x = 88
x = 11
Plug it in to see if it makes equation true
4 (11) + 6 + 4 (11) - 4 = 90
44 + 6 + 44 - 4 = 90
50 + 40 = 90
90 = 90
The answer to ur question will be a square since all diagonals are congruent and bisect each other at right angles
Note:'this is not applicable for the other quadrilaterals from the given options'
Hope this helps u..!!!
Good luck!
Answer:
x axis
Step-by-step explanation:
it will be higher than the first point but not move left or right so by visualising it would be reflected by the x-axis
Answer:x=-30
Step-by-step explanation:
150-x-2x=120+2x
-x-2x+150=2x+120
-3x + 150=2x+120
150=-x +120
-30=x
