Step-by-step explanation:
Answer:
For
we will have positive values only.


Rest are positive so will give positive values out of the modulus function.
Step-by-step explanation:
The absolute value of any number is its positive value only.
As for example
and
both are having equal distance from
in a number line, one on the left other on the right side of the number line but are equidistant from
.
So absolute value of a number is its distance on number line from reference point
.
One by one we will work with all of our question.





So we have to take the positive number out of the modulus function that is also called absolute value.
7^2 = 6^2 + 9^2 - 2(6)(9)cos(m)
-68 = 2(6)(9)cos(m)
cos(m) = -0.6296
m = arcos ( -0.6296)
m = 129.0 degrees
I think it is 3x if I’m not mistaken
