Answer:
Therefore first number is 3 and second number is 18
Step-by-step explanation:
Sum of the two numbers is 21 and Second number is six times the first number
x+6x = 21
7x = 21
x = 21/7
x = 3
substitute x value in 6x to find second number,
= 6x
= 6*3
= 18
Answer:
3x+2y=15--------(1)
4x+2y=20--------(2)
then, 2y=15-3x------(3)
putting value of 2y in equation (2)
4x+15-3x=20
x=5
then after , putting value of x in eq(3)
y=(15-15)/2
y=0

Answer: 
Step-by-step explanation:
Observe the figure attached.
You can identify that the triangle formed is Isosceles, because it has two equal sides.
Notice that you can divide it into two equal right triangles. Now the angle 20° is divided by 2 and you get two equal angles that measure 10°.
To find "x", apply the Trigonometric Identity 
:
Then, the distance between the lighthouses can be represented with:
Substituting the value of "x" into this equation, you get:
