STEP BY STEP EXPLANATION:
4=86⁰ because the lines are parallel.
49⁰+86⁰=180
135=180
180-135
45
5=45⁰
2=49⁰ BECAUSE THE LINES ARE PARALLEL
NOW FOR ANGLE 1
45+86
131
as A & B ARE PARALLEL SO
1=131⁰
HOPE IT HELPS ;)
Answer:
Option (1)
Step-by-step explanation:
The given expression is,
÷
Now we will factor each polynomial separately and substitute the factors in the expression.
x² - 19x + 90 = x² - 10x - 9x + 90
= x(x - 10) - 9(x - 10)
= (x - 10)(x - 9)
x² - 2x - 80 = x² - 10x + 8x - 80
= x(x - 10) + 8(x - 10)
= (x + 8)(x - 10)
x²- x - 72 = x² - 9x + 8x - 72
= x(x - 9) + 8(x - 9)
= (x + 8)(x - 9)
x² + 19x + 90 = x² + 10x + 9x + 90
= x(x + 10) + 9(x + 10)
= (x + 9)(x + 10)
Now by substituting these factors in the given expression
÷ = ÷
= ×
=
Therefore, Option (1) will be the answer.
(a) I think aren't, since it is only 0.8. It is less then Away.
(b) I think it is, since is greater than Home. Hope this helps!
Aye Sir!
The answer is (2x+1)(x-5)
