The supplement of the complement of an angle less the complement of an angle exceeds the quotient of the supplement of the angle
djverab [1.8K]

Complement of an angle = 90° - x.

Supplement of the complement of an angle = 180 - (90 - x).

= 180 - 90 + x

= 90 + x

Supplement of the complement of an angle less the complement of an angle = (90 + x) - (90 - x)

= 90 + x - 90 + x

= 2x

Now, the quotient of the supplement of the angle and the number 3 is \frac{180-x}{3}.

It is given that supplement of the complement of an angle less the complement of an angle exceeds the quotient of the supplement of the angle and the number 3 by 73.

Therefore, 2x = \frac{180x}{3} +73

2x=\frac{180-x+219}{3}

Multiply both sides by 3.

6x = 180 - x + 219

= 399 - x

Add x to both sides.

6x + x = 399

7x = 399

Divide both sides by 7.

x = 57

Hence, the required angle = 57°.

wel

Answer: 270 miles

Step-by-step explanation:

From the question, we are informed that the scale for a map to actual distance is 2 cm to 100 mi and that the driving distance on the map between Los Angeles and Las Vegas is 5.4 cm.

The actual distance, in miles, between Los Angeles and Las Vegas will go thus:

= 5.4cm/2cm × 100mi

= 2.7cm × 100miles

= 270 miles

Francisco and Ryan are stuck simplifying radical expressions. Francisco has simplified to the quantity of x to the one half powe
Wewaii [24]
X to the one half power, over x to the three eighteenth power is equal to x to the one half power, divided by x to the one sixth power, which equals x to the power of (one half minus one sixth), or x to the one third power. 

<span>The twenty seventh root of the quantity of x to the second times x to the third times x to the fourth equals the twenty seventh root of x to the ninth power which equals x to the one third power. </span>

<span>I cannot say whether Francisco and Ryan started with equivalent expressions but on final simplification they ended up the same. One might reasonably assume they started with equivalent expressions, but who knows if they made any mistakes in their simplifications.</span>
