Answer:
Option (1)
Step-by-step explanation:
By using triangle sum theorem in the given triangle,
(5x - 7)° + (11x - 4)° + (3x + 1)° = 180°
(5x + 11x + 3x) - (7 + 4 - 1) = 180
19x - 10 = 180
19x = 190
x = 10
Therefore, (3x + 1)° = 30 + 1
= 30°
(11x - 4)° = 110 - 4
= 106°
(5x - 7)° = 43°
Therefore, Option (1) will be the correct option.

Answer:
12?
Step-by-step explanation:
i might be wrong, but from what it looks like, it shows 3 sections and one is labeled 4.
Answer:
-(1/3)x+1>y
2x-3≥y
If x<12/7 then 2x-3≥y
and if x≥12/7 then -(1/3)x+1>y
Let's make "x" the variable for Maria's age.
And since Maria's father is 20 years older than Maria:
Age of Maria's Father = x + 20.
