Answer:

a: 20

b : 15

Step-by-step explanation:

3*5 = 15

2*5 = 10

Answer:

Let:

  • Present age of B be 'x' years.
  • Present age of A be ( x + 5 ) years.

\:

5 years ago,

  • Age of A = (x + 5) - 5 years = x years.
  • Age of B = ( x - 5 ) years.

\:

<u>According</u><u> to</u><u> the</u><u> question</u><u>,</u><u> </u>

\quad\quad\quad{ \large{ \rm{ \frac{x}{x - 5}  =  \frac{3}{2} }}}

{ \green{ \implies}}{ \sf{2x = 3(x - 5)}}

{ \green{ \implies}}{ \sf{2x = 3x - 15}}

{ \green{ \implies}}{ \sf{3x  -  2x  =  15}}

{ \green{ \implies}}{ \sf{x  =  { \boxed{ \pink{15}}}}}

\:

Therefore,

Present age of B (x) = <u>1</u><u>5</u><u> </u><u>years</u><u>.</u>

Present age of A (x + 5) = <u>2</u><u>0</u><u> </u><u>years</u>.

Answer:

  11.6 cm

Step-by-step explanation:

As the page title tells you, the Pythagorean theorem must be applied more than once. As you know, it tells you the square of the hypotenuse is the sum of the squares of the two sides.

  AD² = ED² +EA²

  EA² = AD²-ED² = 7² -6² = 13

  EA = √13 ≈ 3.606

__

  CD² = ED² +EC²

  EC² = CD² -ED² = 10² -6² = 64

  EC = √64 = 8

__

The length of the horizontal diagonal is ...

  AC = EA +EC = 3.6 +8 = 11.6 . . . cm
