You need the Law of Cosines here and you use it when you have 2 sides and an enclosed angle. The side across from the angle is the one we are looking for. The correct way to express the Law using what we have is the last choice above. Side RT is the unknown, and it is across from the angle that is enclosed between the 2 other sides.
No it doesn't become positive

Step-by-step explanation:
Hope this helps!!
Step-by-step explanation:
plug in y
6=1/3x+11/15
multiply both sides by 15 to get rid of the fraction
90 = 5x +11
move terms to make them like terms
-5x =11- 90
-5x = -79
divide both sides by -5
evaluate for x
Answer:
The 5th term is 16
Step-by-step explanation:
Given data
a= 12
say we want to find the fifth term
n=5
d= 1
The expression for the nth term given as
an = a + (n – 1) × d
Substitute
an= 12+(5-1)1
an= 12+4
an= 16
