Answer:

The answer is the option D

x=7, y=4

Step-by-step explanation:

we know that

If the triangles are congruent

then

The corresponding sides are congruent

AC=EF, BC=DE

substitute the values

5x-5y=2y+7 ------->5x=7y+7 --------> equation A

6y-8=2y+8 -------> 6y-2y=8+8 -------> y=4

Substitute the value of y in the equation A and solve for x

5x=7(4)+7

x=35/5

x=7

mr_godi [17]

Answer:

Distance between boat and light house = 223.88 meter (Approx.)

Step-by-step explanation:

Given:

Height of light house = 60 meters

Angle of depression to boat = 15°

Find:

Distance between boat and light house

Computation:

Using trigonometry application:

Tanθ = Perpendicular / Base

Tan 15 = Height of light house / Distance between boat and light house

0.268 = 60 / Distance between boat and light house

Distance between boat and light house = 60 / 0.268

Distance between boat and light house = 223.88 meter (Approx.)
