Answer:
124 degrees
Step-by-step explanation:
180 degrees is a straight line
the given angle is 56 degrees
so, all you do is subtract
180 - 56 = 124
to double check,
56 + 124 = 180
X= 124
Because these angles are alternate interior angles we know that X+56 will equal 180, so to solve:
180 - 56= 124
What?
X = -
v=9
is there a question?
The expression (5x + 4)^3 in expanded form is 125 x3 + 300 x2 + 240 x + 64. The expression will have also a root of x = -4/5. This is the form of trinomial expansion and can be solve by multiplying the the term 3 times.
