My triangle solver says EF ≈ 7.5 ft.
_____
The law of cosines is usually used for this.
EF^2 = DE^2 +DF^2 -2*DE*DF*cos(D)
.. = 6^2 +11^2 -2*6*11*cos(40°)
.. ≈ 55.88
EF ≈ √55.88 ≈ 7.5 . . . ft
C. because each month it was increased by an equal number of integer.....
Add 9+9 and it eat either equals 18 or 81
<span><span>Yes, it meets the requirements. 1/12 simplifies to 0.0833 and 4/50 simplifies to .08. .</span>413398#respond</span>
Radical expression are expressions that contains square root. The value of x from the given radical expression is 3
<h3>Radical equations and expression</h3>
Given the equation expressed as:
x = 2 + √x - 2
Subtract 2 from both sides
x - 2 = √x - 2
Square both sides
(x-2)^2 = x - 2
x - 2 = 1
x = 1 + 2
x = 3
Hence the value of x from the given radical expression is 3
