In the triangle below, what is the length of the side opposite the 30 degree angle?
Vitek1552 [10]

Answer:

A. 3/2

Step-by-step explanation:

To find the lenght of the side opposing the 30° angle, you need to use trigonometry, since it's a right-angled triangle. You have your 30° angle and you have the side beside : therefore, you can use the sine :

sin(30) x 3 = ?

0,5 x 3 = ?

1,5 = ?

1,5 = 3/2

kirill115 [55]

Answer:

Step-by-step explanation:

Angles around a point add up to 360

x + 53 + 37 + 139 = 360

               x + 229 = 360

                        x = 360 - 229

                        x = 131

A recursive arithmetic sequence is defined ad f(1)=6, f(n+1)=f(n)+5 for n&gt;1. The first four terms of the sequence are shown i
Dennis_Churaev [7]
Write the first few terms of the sequence.
f₁ = 6
f₂ = f₁ + 5 = 11
f₃ = f₂ + 5 = 16
f₄ = f₃ + 5 = 21
and so on

The sequence is
6, 11, 16, 21, ...,
This is an arithmetic sequence with a common difference of 5.

In function notation, the sequence is
f_{n+1} = 6 + 5n, \\ \, n=0,1,2, \, ...,

This represents the equation of a straight line with n as the independent variable and f as the dependent variable.
The slope is 5. 
A graph of the line is shown below.

Answer:
The sequence is f_{n+1} = 6 + 5n, \,\, n=0,1,2, \, ...,
The slope is 5.
