Drag each length to the correct location on the triangle. Each length can be used more than once, but not all lengths will be us
LUCKY_DIMON [66]

The sides of the triangle are 5√2 , 5√2 and 10.

<h3>What is a Triangle ?</h3>

A triangle is a polygon with three sides , three vertices and three angles , When one angle is equal to 90 degree , it is called a Right Angled Triangle.

It is given that two angles given is 45 and 45 degree each so by using trigonometric ratios the sides can be calculated.

From the data given in the image

sin 45 ° = 5√2 / x

x = 5√2 / sin 45°

x = 10

The hypotenuse = 10

From The Pythagoras theorem

10² = (5√2)² + y²

y = (5√2) unit

Therefore the sides are 5√2 , 5√2 and 10.

Estimate the rate at which the total personal income is rising in a metropolitan area. In 1999, the population of this area was
Natasha2012 [34]

Answer:

X=\$1.64*10^9

Step-by-step explanation:

From the question we are told that:

Population size P=918000

Rate of Population increase  \frac{dP}{dt}=9700

Average annual income I= \$34,549

Rate of annual income increase  \frac{dI}{dt}=\$1300

Generally the equation for Total Income is mathematically given by

X=P \frac{dI}{dt}+I \frac{dP}{dt}

X=918000*1400+(9200*30593)

X=\$1.64*10^9

Find the 22nd term of the following sequence:<br> 5, 8, 11, ...<br> 63 <br> 71<br> 14<br> 68
Wittaler [7]

68 is the 22nd term of the following sequence.

<u>Step-by-step explanation:</u>

  • The given sequence is with the same common difference between the two consecutive number in the series thus it is said to be the  Arithmetic progression ( AP).
  • For finding the nth term in the AP we have a formula tn = a + (n-1) × d
  • Here a is the first term , n is the number of the term to be founded and d is the common difference between the two consecutive number in the series.
  • Thus here tn = 5 + ( 22 - 1 ) × 3.
  • On subtracting we get tn = 5 + (21 ) × 3
  • On multiplying we get tn = 5 + 63
  • After adding we get tn = 68. It is the 22nd term in the given series.
