Finishing the angles of the smaller triangle if E is 90 and F is 30 then G needs to be 180-90-30 = 60 degrees.
Angles G and C are supplementary angles which need to equal 180 degrees
Angle c = 180-g = 180-60 = 120
Angle c = 120 degrees.
Answer:
A square root of 16 is 4 would represent the truth value. The only square root of 9 is -3 is not true because the square root of 9 could be 3 or -3.
Step-by-step explanation:
The way that i learned this was first set > to = worry about it later
so 9x-7i=3(3x-7u)
so 9x-7i=9x-21u
the x cancel out
so 7i= -21u
now isolate the variable
so
7i/-21=u
so
u=-i/3
C is the answer. Solutions to a polynomial are numbers that, when plugged into the equation, make the equation equal zero
So if you plug 3, -1, or 2 into x^3 - 4x^2 + x + 6, it will equal zero.
