What are the values the values of a and b?
Setler [38]
The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

\frac{20}{a} = \frac{21}{20}

Solving,

21a =(20)(20) \\ 21a = 400 \\ a = \frac{400}{21}

To find  b,  use the fact that  b  is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it,  a.

\frac{b}{a} = \frac{21+a}{b}

A little arithmetic shows that 21+a = \frac{841}{21}.

\frac{b}{\frac{400}{21}} = \frac{\frac{841}{21}}{b} \\ b^2 = \frac{336400}{441} \\ b=\frac{580}{21}

Can anyone please help me with this.
geniusboy [140]

Answer:


Step-by-step explanation:

Givens

The triangle is equilateral.                         Given

<K = < M = 60                                             Property of an equilateral triangle.

IE = IE                                                           Reflexive property

Proof

  • <IEK = <IEM  = 90                                  Property of perpendicular
  • <EIK = 180 - 60 - 90                              All triangles have 180 degrees
  • <EIK = 30                                               Subtraction
  • <MIK = 180 - 60 - 90                             All triangles have 180 degrees
  • <MIK = 30                                              Subtraction
  • <MIE = <KIE                                           Both = 30 degrees
  • IE = IE                                                     Reflexive property
  • <IEK = <MEI                                            Both are right angles.
  • ΔMIK ≡ΔKIE                                            ASA

Two cars leave the same parking lot, with one heading north and the other heading east. After several minutes, the eastbound car
4vir4ik [10]

The northbound car has traveled a distance of 6.2 miles.

Step-by-step explanation:

Step 1:

The eastbound car has traveled a distance of 5 miles and if a straight line is drawn between the two car's positions it would measure 8 miles.

This forms a triangle which has a hypotenuse measuring 8 miles while one of the other sides measures 5 miles.

Assume the distance traveled by the northbound car is x miles.

Step 2:

According to Pythagoras' theorem,

x^{2} +5^{2} =8^{2} , x^{2}  = 8^{2} -5^{2} = 64-25.

x^{2} =39, x=6.2449.

So the northbound car has traveled a distance of 6.244 miles. Rounding this off, we get 6.2 miles.

Which is the greatest common factor of 12 and 88​
tester [92]

4 will be your answer

Explanation:

The factors of 12 are 1, 2, 3, 4, 6, 12

The factors of 88 are 1, 2, 4, 8, 11, 22, 44, 88.

So, as we can see, the Greatest Common Factor or Divisor is 4, because it is the greatest number that divides evenly into all of them.

hope it helped  :D
