Answer:

1/5, 1/6, 1/7, 1/8

Step-by-step explanation:

The formula for the sequence is (n+3)!/ (n+4)!

The first terms uses n=1

a1 = (1+3)!/ (1+4)! = 4!/5! = (4*3*2*1)/(5*4*3*2*1) = 1/5


The first terms uses n=2

a2 = (2+3)!/ (2+4)! = 5!/6! = (5*4*3*2*1)/(6*5*4*3*2*1) = 1/6


The first terms uses n=3

a3 = (3+3)!/ (3+4)! = 6!/7! = (6*5*4*3*2*1)/(7*6*5*4*3*2*1) = 1/7


The first terms uses n=4

a4 = (4+3)!/ (4+4)! = 7!/8! = (7*6*5*4*3*2*1)/(8*7*6*5*4*3*2*1) = 1/8

A triangular flower garden has an area of 28 m². Two of its edges are 14 metres and
velikii [3]

Answer:

30°

Step-by-step explanation:

Area of a triangle can be found using either of the formula:

1. area = 1/2 x base x height

2. area = 1/2 ab sin c

Since we know the length of the two edges, we will use the 2nd formula:

Area = 1/2 ab sin c

Substituting the known values:

28 = 1/2 (14)(8) sin c

28 = 56 sin c

sin c = 0.5

c = 30°
