AB = 24
BC = 45
AC = 51
cos C = adjacent / hypotenuse
cos C = BC / AC
cos C = 45/51
I calculated with my teacher and somehow we could onu get 667.22
Answer: the answer is 20
Step-by-step explanation:
Use order of operations and divide 8 by 2 and you get 4. Then use the PEMDAS (parentheses,exponents,multiplacation,division,addition, subtraction) method. Go left to right. And solve. :) I hope this helps
Answer:
y=-4x-17
Step-by-step explanation:
You want to find the equation for a line that has a slope of -4 and a y-intercept of -17.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
All you really have to do here is
replace m with -4, which is the slope you gave, and
replace b with -17, the y-intercept you gave,
in the equation y=mx+b.
The equation of the line that has a slope of -4 and a y-intercept of -17 is:
y=-4x-17.
