It will be 69 degrees.
(x-1)+x+43=180
2x+42=180
2x=138
x=69
Cot theta is 1 over tan theta.The only way for 1/tan theta to be undefined is for tan theta = 0. - answers
Ok, so after you do -8a+5a, you also have to do 6 -35, getting the equation
-29-3a
Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.
<h3>Slope of a function</h3>
Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.
The formula for expressing the slope of a function is given as;
f'(x) = f(b)-f(a)/b-a
a and b are the intervals
The slope can also be expressed as a function of its coordinate (x, y)
Slope = y2-y1/x2-x1
