Answer:
-5
Step-by-step explanation:
The equation for slope is:

We can plug in the given coordinates into the equation:

-2/(a+b)
Explanation: you are dividing negative two by the sum of a and b so you would put a+b in parentheses as the denominator and then put -2 as the numerator
Let the required number is 2x ,
According to the condition,
➡ 10 times the sum of half of 2x and 6 = 8

Therefore the value of x is -5.2
And, required number is -5.2
The interior of a triangle = 180°
So 180° - 85° -50° = 45°
c. 45 degrees
