AC = 3.67

Step-by-step explanation:

We use trig functions.

We want to find the side opposite to 70 degrees and we are given the side next to 70 degrees.

We use tan as that functions take accounts to both sides.

tan (θ) = opposite/adjacent

tan (70) = x/3

x = 3*tan (70) = 3.67

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
