Answer:
x=4
x=17.9
Step-by-step explanation:
For the first diagram.
cos(45°)=x/4√2
x=4√2cos(45°)
x=4
For the second diagram
tan(38°)=14/x
0.781=14/x
x=14/0.781=17.9

It makes an AP with the first term of 1 and common difference of 3
The formula for this AP is:
- aₙ = 1 + 3(n-1) = 1 + 3n - 3 = 3n - 2
From the given options, only one is not in the same format:
because
- 21 = 3n - 2 ⇒ 3n = 23 and n= 23/3 is not an integer
Answer is: c) 13
