Step-by-step explanation:
x + x + 26 = 90
2x = 64
x = 32 degrees, this is one angle.
32 + 26 = 58 degrees. This is our second angle.
32 + 58 = 90 degrees.
An arithmetic sequence (a_n) is as follows:

where

is the first term and d is the constant difference,
thus, we see that the n'th term of an arithmetic sequence is

in our particular case d=5, the third term is 8, so we have:

and the general term is

,
Answer: first term is -2, n'th term is -2+5(n-1)
The surface area of a shape is basically the sum of all the areas on a shape.
We’ve been given that the side is 17 mm.
An area of a square is A=s^2, in which s means side. So we do 17^2 to get the area of ONE of the squares.
Once we do that we get that the area of 1 square is 289.
Since there are 6 squares we need to multiply 289 by 6.
Therefore,
SA=1734mm^2
What's the question that needs solving?
Hi friend,
Repeating geometric patterns in a solid are called Deposition.
It is also called as desublimation.
Hope this helps you!
