Answer:

Step-by-step explanation:

given tanB= 4/3

so sinB=4/5

n cosB=3/5

given BC=15

BA=BC*cosB

=15*3/5

AC=BC*sinA

=15*4/5

=12

Triangle ABC and DBE are similar by AAA

DB= BA-AD

=9-3

DB/BA=DE/AC

6/9=DE/12

DE=12*6/9

Find the value of x when a⊥b and b||c.

dem82 [27]

Answer: 8

Step-by-step explanation: Because a is perpendicular to b, the value of 9x + 18 = 90. If we subtract 18 from both sides, it becomes 9x = 72. Divide by 9 on both sides to get 8

The correct answer is: [B]: " 9.6 cm " .
____________________________________________________________

Explanation:
____________________________________________________________

Let "FH" = "x" ; for which we wish to solve.

45 cm / 12 cm = 36 cm / "x" (in "cm") ;

To solve for "x" ;

Cross--multiply:

Note: Given:

" $\frac{a}{b} = \frac{c}{d}$ " ; " ad = bc " ; (b ≠ 0 ; d ≠ 0) ;

So: " 45x = 12 * 36 " ;

→ 45x = 432 ;

Divide each side of the equation by "45" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 45x / 45 = 432 / 45 ;

→ x = 9.6 cm ;
___________________________________________________________
→ which corresponds with:

→ Answer choice: [B]: " 9.6 cm " .
