Opposite sides of a parallelogram are equal in length so 
the perimeter = 2*9 + 2*5 = 28 ft Answer

Find two numbers if their sum is 6.1 and their difference is 1.6
Radda [10]
For this case, the first thing we must do is define variables:
 x: unknown number (1)
 y: unknown number (2)
 We now write the equations that model the problem:
 their sum is 6.1:
 x + y = 6.1

 their difference is 1.6:
 x - y = 1.6

 Solving the system we have:
 We add both equations:
 x + x = 6.1 + 1.6

2x = 7.7

x = 7.7 / 2

x = 3.85
 Then, we look for the value of y using any of the equations:
 x - y = 1.6

y = x - 1.6

y = 3.85 - 1.6

y = 2.25
 Answer:
 
The numbers are:
 
x = 3.85

y = 2.25

Need help on this please help
kobusy [5.1K]

Answer:

The measure of ∠A is 127°.

Step-by-step explanation:

The interior angles of a triangle always add up to 180°. Since you can fix <em>three</em> triangles into a pentagon, the sum of its interior of angles is 540° You could also look at how many angles there are (5), multiply that number by 180°, then subtract 360° from the product.

540° - (113° + 80° + 130° + 90°) = ∠A

540° - 413° = 127°

∠A = 127°

<em>Hope this helps,</em>
