Atriangle having sides of 2, 2, and 3 contains

Answer with explanation:

It is given that the triangle has three sides having  side length 2, 2 and 3 units.

Since two sides of triangle is equal, So it is an Isosceles triangle.

To check whether it has any of the angle is right angle or Obtuse angle, we will use Cosine formula.

Since Angle Opposite to Larger side is greater.Angle Opposite to Larger side 3 units be m°.

⇒→Since , cosine of angle between  two sides ,2 and 2 is , Negative.It means it is an Obtuse Angle.

So, other two angles will be acute.

So, the given triangle having sides 2,2,and 3 is Obtuse Isosceles Triangle.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
