Answer:
The answer to your question is ∠2 = 130°
Step-by-step explanation:
Data
m∠1 + m∠5 = 100
From the picture, we notice that ∠1 and ∠5 are corresponding angles so they measure the same.
∠1 + ∠1 = 100
2∠1 = 100
∠1 = 100/2
∠1 = 50°
From the picture, we know that ∠1 and ∠2 are supplementary, then,
∠1 + ∠2 = 180
-Solve for ∠2
∠2 = 180 - 50
-Result
∠2 = 130°
Step-by-step explanation:
length=x
width=x-1
x + x + (x-1) + (x-1) = 54
4x - 2 = 54
4x = 56
x = 14 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
Perimeter= x + x + (x-1) + (x-1)
54 ft = 14 + 14 + (14 - 1) + (14 - 1)
54 ft = 28 + (13 +13)
54 ft = 54 ft

In this exercise we have to use the knowledge of geometric progression to find three specific numbers, in this way we can say that these numbers correspond to;
Then using the formula of the geometric progression we find that:
now, the differences between the terms must be the same:
and now, when we increase the third term by 9,so we have:
Now we use that identity in the first equation :
The general solution for a quadratic equation is
We have that:
so, put the numbers in the formula we find:
