Answer:

7(x+3)

Step-by-step explanation:

7x+21

7x = 7*x

21 = 7*3

We can factor out a 7 from both terms.  What remains is what is inside the parentheses

7(x+3)

When flying at an altitude of 5 miles, the lines of sight to the horizon looking north and south make about a 173.7 degree angle
oksian1 [2.3K]
5 miles high is one of the sides of a triangle depending on accuracy level
h^2=x^2+y^2
we don't have 2 distances
Tan A=O/a
O=a tan A
We solve for O because the angle is at the top of the line going up and we want the opposite angle that is along the ground
O=5×tan(173.7/2)=90.854033512
The distance he can see is:
90.85*2~181.7 miles

Now we need to find the distance between lines:
The north south distance between each line is 69 miles
thus the number of degrees he will see will be:
181.7/69
=2 19/30

If m∠BEC = 9z + 45 in rhombus ABCD, find the value of z. Help me PLEASE!!!! And can you show me how you did it Please!
cupoosta [38]
The diagonals of a rhombus bisect each other at right angles, therefore m∠BEC=90°

9z + 45 = 90
9z = 90 - 45
9z = 45
z = 45/9
z = 5
