<em>x = 8</em>
<em>cos60° = x/16</em>
<em>1/2 = x/16</em>
<em>2x = 16</em>
<em>x = 16 : 2</em>
Answer:
Step-by-step explanation:
Multiplying both sides by 16.
Simplifying the equation.

Use term formula for +/-
Tn = a + (n-1)d
n= number of term
a= first number in sequence
d= difference between each number
T55 = 16 + (55-1)5
T55 = 16 + 270
=286
15x - 70 = 500
