whats m<ABC if u have (7x-1) and (3x-9)?
To find the measure of angle ABC, you first need to determine the relationship between those two expressions, (7x - 1) and (3x - 9). Assuming that m<ABC is a geometric angle, we can use the fact that the sum of the angles of a triangle is always 180 degrees.
So, if we have the measure of angle ABC, we can set up the equation: (7x - 1) + (3x - 9) + m<ABC = 180.
Now, let's simplify the equation: 10x - 10 + m<ABC = 180.
To solve for m<ABC, isolate the variable by subtracting 10x and adding 10 from both sides: m<ABC = 180 - 10x + 10.
The final solution for m<ABC in terms of x is m<ABC = 190 - 10x.
