Answer:
x = 18.46
Step-by-step explanation:
Find the last angle of the triangle.
180-90-72 = 18
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos(b) = adj/hyp
CosB=a/c rewrite to get
6/CosB (72) = 19.41
Find the last side of the triangle using the Pythagorean theorem.
b=square root c^2 - a^2
b=square root 376.99 - 36
b= 18.46
Answer:
-3n + 18
Step-by-step explanation:
an = dn + (a - d)
The difference is -3.
The first term is 15.
an = -3n + (15- (-3))
an = -3n + 15 + 3
an = -3n + 18
