Can somebody help me with this?

Step-by-step explanation:

Hey there!

By looking through figure, l and m are parallel lines and a transversal line passes through the lines.

Now,

7x + 12° = 12x - 28°( alternate angles are equal)

12°+28° = 12x - 7x

40° = 5x

$x = \frac{40}{5}$

Therefore, x = 8°

Now,

12x - 28° + 9y - 77 = 180° ( being linear pair)

12×8° - 28° + 9y -77° = 180°

96° - 28° + 9y - 77° = 180°

-9 + 9y = 180°

9y = 180° + 9°

y = 189°/9

Therefore, y = 21°

Therefore, X = 8° and y= 21° .

Hope it helps....

What two integers have a sum of negative ten and a product of negative seventy five?

Natali [406]

A+b=-10
ab=-75

a=-75/b
-75/b + b = -10

-75/b + b²/b = -10b/b
b²+10b-75=0

(b+15)(b-5)=0
b+15=0 or b-5=0,
b= -15, a=5
