Hello from MrBillDoesMath!

Answer: x = -1

Discussion:

Let x be the unknown integer. Then

5 x^2 + 3x = 2 or

5x^2 + 3x -2 = 0 or (factoring)

(x+1) ( 5x -2) = 0

so x = -1 (the other value of x, +2/5, is not an integer)

Thank you,

MrB

find the measures of an angle between 0°and 360° coterminal with an angle of -271° in standard position

alisha [4.7K]

We are given angle in standard position as

$\theta=-271$

we know that one complete rotation is 360

so, to find angle between 0 and 360

so, we will add 360 to get co-terminal angle

so, co-terminal angle is

$=\theta +360$

now, we can plug value

co-terminal angle is

$=-271 +360$

$=89$ .............Answer
