Step-by-step explanation:
Given:
Complementary angle = 68'
Angle measure = 90' - 68' = 22'
Supplementary angle = 180' - 22' = 158'
Angle classification = Acute angle
Given:
Supplementary angle = 161'
Angle measure = 180' - 161' = 19'
Complementary angle = 90' - 19' = 71'
Angle classification = Acute angle
Given:
Angle measure = 136'
Angle classification = Obtuse angle
Complementary angle = 136' - 90' = 46'
Supplementary angle = 180' - 136' = 44'
Hi again
x² - 2x - 8
Factor
= (x + 2)(x -4)
Answer : A is the correct option.
If you wanna check if A is the right answer, I will solve it for you and it will you give you the exact answer which will be x² - 2x - 8
(x+2)(x-4)
Distribute
(x)(x) + (x)(-4)+(2)(x)+(2)(-4)
= x² - 4x + 2x - 8
= x² - 2x - 8
Here it is, we find the exam answer.
Thus, (x+2)(x-4) is the reciprocal of x² -2x - 8
I hope that's help !
Please include the number or a photograph or it! Thank you!
