Answer:
50
Step-by-step explanation:
Adds up to 360 degrees
for the first term:
n= 1 there is 1 item
n=2 there are 2+1 = 3 items
n = 3 there are 3+2+1 = 3+2 = 6 items
n = 4 there are 4+3+2+1 = 4+6 = 10 items
We are adding the "n" term each time
n = 5 10+5 = 15
n= 6 15+6 = 21
n = 7 21+7 = 28
n = 8 28+8 = 36
There would be 36 items in the 8th step
4x + 6 = -26
I'm not sure if your supposed to solve, but I will anyways :)
4x + 6 = -26
-6 -6
4x = -32
x = -8
Hope this helps!
The angle of elevation for the given figure will be 68.198°.
<h3>What is a trigonometric function?</h3>
The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.
The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.
The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.
Given the figure is making a right-angle triangle with a base of 10m and a height of 45 - 20 = 25 m
By trigonometric function tan
Tanθ = 25/10
θ = 68.198°
Hence "The angle of elevation for the given figure will be 68.198°".
