So we can only find x if other two angles of triangle is given.
In angle B as u can see boxed shape angle is there then it probably means it's a 90° angle.
We know sum of angles of triangle = 180°
{Reson :-
There's a formula to fund sum of angles of figure
- (n-2) × 180
- (3 -2) × 180
- 1 × 180
- 180°
}
Now Let's proceed
![\boxed{ \rm Side_1+Side_2+Side_3 = 180\degree}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Crm%20Side_1%2BSide_2%2BSide_3%20%3D%20180%5Cdegree%7D)
Fill all the given values

Answer:
= 5n - 1
Step-by-step explanation:
There is a common difference between consecutive terms , that is
9 - 4 = 14 - 9 = 19 - 14 = 5
This indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 5 , then
= 4 + 5(n - 1) = 4 + 5n - 5 = 5n - 1
Z = 17.
2(4z -8) = 120
8z -16 = 120
z -2 = 15
z = 17
