8 0

Answer:

D. 126

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

30 + 24 + 3x - 9 = 180 add like terms

45 + 3x = 180 subtract 45 from both sides

3x = 135 divide both sides by 3

x = 45 and to find angle UVW replace x with 45

3*45 - 9 = 126

If line L is perpendicular to line m and the slope of line L is undefined, what is the slope of line m?
Delicious77 [7]

Step-by-step explanation:

mL = Undefined

mM = ?

mL × mM = -1

mM = -1 ÷ mL
