Find the value of x.
104°
40°
x°
TRIANGLE

36^0

Step-by-step explanation:

104^0+40^0+x^0=180^0

or, 144^0+x^0=180^0

or,x^0=180^0- 144^0

or,x^0=36^0

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
