Answer:
x=75
Step-by-step explanation:
35+45+x=2x+5
80+x=2x+5
80-5=2x-x
75=x
I hope I was of help and plz mark this answer as brainliest
We are given
Angles α and β are angles in standard position
and
α terminates in Quadrant II
β terminates in Quadrant I
and we have
we can use triangle and find cos(α)
we get
and we have
we can draw triangle
now, we can use formula
now, we can plug values
now, we can simplify it

You have to distribute it or use FOIL (if u know that method). This is basically factoring.
for instance:
(2x-9)×(x+4)
first: 2x × x = 2x^2
second: 2x × 4 = 8x
third: -9 × x = -9x
forth: -9 × 4 = -36
now combine like terms.
2x^2 + 8x -9x - 36
(8x and -9x are like terms)
(add the two together, which is -1x or -x)
2x^2 -x -36 is ur answer
now do this same method for the rest
A. -6 is the answer of the day
