ANSWER : x = 44 degrees

The area of a triangle should equal 180.
If you subtract 14 and 30 from 180 it’ll give you 136.
Subtract that from 180 n you’ll get 44

OF JUST ADD BOTH ANGLES TOGETHER FOR THE ANSWER LOL

Ali bought a music system for rs 6375.00 and spent rs 75.00 on transportation . He sold it for 6400.00 . Find his profit or loss

pentagon [3]

Answer: Loss percent = 0.775%

Step-by-step explanation:

Here,

Total cost = Purchasing price + transportation

⇒ Total cost = 6375 + 75

⇒ Total cost = $ 6450

Selling price = $ 6400

Total cost > Selling price, hence it is a loss.

Loss percent formula :

$Loss\% =\dfrac{\text{Loss}}{Total\ cost}\times100\\\\=\dfrac{Total\ cost - Selling price}{Total \ cost}\times100\\\\=\dfrac{6450-6400}{6450}\times100\\\\=\dfrac{50}{6450}\times100=0.775\%$

Hence, Loss percent = 0.775%

the perimeter of a rectangle is 56 m. if the width were doubled and the length were increased by 8 m, then the perimeter would b

Natasha2012 [34]

----------------------------------------------------------------
Define x and y:
----------------------------------------------------------------
Let the length be x.
Let the width be y.

----------------------------------------------------------------
Formula:
----------------------------------------------------------------
Perimeter = 2(Length + Width)

----------------------------------------------------------------
Construct equations and solve for x and y:
----------------------------------------------------------------
2x + 2y = 56 ---------------------- (1)
2(x+8) + 4y = 82 -----------------------(2)

----------------------------------------------------------------
From equation 1:
----------------------------------------------------------------
2x + 2y = 56
x + y = 28
x = 28 - y

----------------------------------------------------------------
From equation 2:
----------------------------------------------------------------
2(x+8) + 4y = 82
2x + 16 + 4y = 82
2x + 4y = 66
x + 2y = 33

----------------------------------------------------------------
Substitute x = 28 - y into equation 2:
----------------------------------------------------------------
x + 2y = 33
(28 - y) + 2y = 33
28 - y + 2y = 33
y = 5

----------------------------------------------------------------
Substitute y = 5 into equation 1:
----------------------------------------------------------------
x = 28 - y
x = 28 - 5
x = 23

----------------------------------------------------------------
Find Length and Width
----------------------------------------------------------------
Length = x = 23 m
Width = y = 5m

----------------------------------------------------------------
Answer: Length = 23m and Width = 5m
----------------------------------------------------------------
