Answer:
The angle will be 130 degrees
Step-by-step explanation:
50 at the center translates to 50 at the outer rim.
this means it will be 310-50 divided by 2
260 divided by 2 equals 130
Answer:
In the given expression 
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8
Step-by-step explanation:
We are given the expression 
We need to give variable, coefficients and constant.
Variable: The value of variable may change. It can be represented by x, y or any other letter
Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient
Constant: It is fixed value. It cannot be changed.
So, in the given expression 
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8
There is no graph for us to see
There is a math graping app called desmos it can help you graph the equation and give you the intercepts
