Answer:

see explanation

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal

(a)

$\frac{AB}{DE}$ = $\frac{BC}{EF}$ , substitute values

$\frac{AB}{17.64}$ = $\frac{6.3}{13.23}$ ( cross- multiply )

13.23AB = 111.132 ( divide both sides by 13.23 )

AB = 8.4

(b)

$\frac{DF}{AC}$ = $\frac{EF}{BC}$ , substitute values

$\frac{DF}{4.1}$ = $\frac{13.23}{6.3}$ ( cross- multiply )

6.3DF = 54.243 ( divide both sides by 6.3 )

DF = 8.61

Solve and show all work |2×+3| -6=11

mash [69]

Answer:

x = -10; x = 7

Step-by-step explanation:

|2x + 3| - 6 =11

Add 6 to each side.

|2x + 3| = 17

Apply the absolute rule: If |x| = a, then x = a or x = -a.

(1) 2x + 3 = 17 (2) 2x + 3 = -17

Subtract 3 from each side

2x = 14 2x = -20

Divide each side by 2

x = 7 x = -10

<em>Check: </em>

(1) |2(7) + 3| - 6 = 11 (2) |2(-10) + 3| - 6 = 11

|14 + 3| - 6 = 11 |-20 + 3| - 6 = 11

|17| - 6 = 11 |-17| - 6 = 1 1

17 - 6 = 11 17 - 6 = 11

11 = 11 11 = 11

The angle of elevation from a ship to a

GREYUIT [131]

Answer:

Step-by-step explanation:

The angle we are given is 2° and we are given the opposite leg, 135 ft. We are trying to find the hypotenuse length- the diagonal distance from the ship to the lighthouse.

So, we use SOHCAHTOA with sine:

$sin(2)=\frac{opp}{hyp}= \frac{135}{x}$

$x = \frac{135}{sin(2)} = 3868.251 ft$

Keep in mind that the angle is in degrees. Also, the number is large because of the extremely short angle.
