<span>x = -0.875. That is what x equals.</span>
Multiply numerator and denominator by sin(x) * cos(x), getting:
((sin(x) * cos(x)) - cos^2(x) / (((sin^2(x)) - (sin(x) * cos(x))) =
(cos(x) * (sin(x) - cos(x)))
------------------------------------
(sin(x) * (sin(x) - cos(x)))
and after you cancel the two identical terms (sin(x) - cos(x)), you have:
cos(x)
----------- = cot(x) <--------------- Answer
sin(x)
X = 60 degrees.
the triangle is equiangular. All angles are 60 degrees
Answer:
If I am correct the perimeter is 24
Step-by-step explanation:
Count how many are on the top which is 9. 2 sides are the same so 9+9=18. (OUR FIRST PART) Now the sides are 5 but WE ALREADY COUNTED 2 ON EACH SIDE SO THAT IS 3=3=6. Now add. 18+6= 24
