Answer:
70°
Step-by-step explanation:
∠A =112°,
Exterior angle to angle B is 2x, therefore ∠B = 180 -2x (angle on straight line)
Exterior angle to angle C is 2x + 12, therefore ∠C = 180 -(2x +12) (angle on straight line) = 180 - 12 -2x = 168 - 2x
∠A + ∠B + ∠C = 180 (sum o angles in a triangle)
112 + 180 - 2x + 168 - 2x = 180
460 - 4x = 180
4x = 460 - 180 = 280
x = 280/4 = 70
x = 70°

Answer : Image 3
Which table shows a function that is decreasing over the interval (−2, 0)?
We look at the interval -2 to 0 on x
In option 1 table , f(x) is 0 then -5 and then becomes 0
It means -2 to -1 , f(x) decreases but from -1 to 0 y values increases
In option 2 table , f(x) is increasing from -15 to -5
In option 3 table, f(x) values goes on decreasing over the interval -2 to 0
So , option 3 table shows a function that is decreasing over the interval (−2, 0)

Answer:
The number of apples did Lisa eat is 8
Step-by-step explanation:
Given as :
Total number of apple to eat in contest between Charles and Lisa = 18
Let The number of apples ate by Charles = x
So, The number of apples ate by Lisa = x + 2
Now,
Total number of apples to eat in contest between Charles and Lisa = 18
Or, x + ( x + 2 ) = 18
Or, ( x + x ) + 2 = 18
Or, 2 x = 18 - 2 = 16
∴ x = 
I.e x = 8
So , The number of apples ate by Lisa = x = 8
The number of apples ate by Lisa = x + 2 = 8 + 2 = 10
Hence The number of apples did Lisa eat is 8 Answer
