<span>The length of a diagonal on a square represents a hypotenuse of the right triangle whose legs are equal
And also this triangle is a half of the square
The length of one side of a square = 90 feet

∴ d² = 90² + 90² = 2 * 90²
∴ d = 90√2

∴ </span><span>The equations can be used to calculate d = 90√2

In general for any square has length of side = x
The diagonal of the square = d = x√2</span>

Suppose the probability of an IRS audit is 3.8 percent for U.S. taxpayers who file form 1040 and who earned $100,000 or more. Wh
brilliants [131]

Answer:

a) The odds that such a taxpayer will be audited is 4%.

b) The odds against such a taxpayer being audited is 96%.

Step-by-step explanation:

a) Data and Calculations:

The probability of an IRS audit = 3.8% for U.S. taxpayers who file form 1040 and earned $100,000.

This is the same as the odds that such a taxpayer will be audited.  Odds is the likelihood or chance that an event will take place.

b) The probability of not being audited is 100 - 3.8% = 96.2%

The odd against being audited is the likelihood or chance that an event will not take place.

Whose correct &amp; whats an equation to solve for x.
Effectus [21]

Answer:

Step-by-step explanation:

x is the side opposite the angle of 12 degrees

we know the hypotenus  is 20 ft

we don't know what the side length that is adjacent to the angle

----------------

ADJ/HYP = cos (of the angle)

OPP/HYP  = sin (of the angle)

sin/cos = tan (of the angle) = ( OPP/HYP) / (ADJ/HYP)  = OPP/ ADJ

How would we solve for x the side opposite the angle?

So who is right?
