Answer:
27 Degree
Step-by-step explanation:
First Draw the graph (If you want)
Tan is what we have to use because TAN = Opposite / Adjacent
TanA=2/4
TanA=1/2
TanA=0.5
Tan^-1 x (0.5)
<A= 26.565...
ROUND TO THE NEAREST DEGREE = 27 Degrees
Answer:
80
Step-by-step explanation:first you multiply from left to right and then you will get you answer
Answer:
19
Step-by-step explanation:
I took one for the team
The perimeter is the total of adding all of the side lengths together.
A square has 4 equal side lengths.
So the perimeter of a square is:
P = s + s + s + s or P = 4s
[P = perimeter s = side lengths of the square]
Since you know the side length of the square is (x + 2 1/4), you can replace s with (x + 2 1/4)
P = 4s
P = 4(x + 2 1/4) Multiply 4 into (x + 2 1/4)
P = 4x + 8 4/4
P = 4x + 9
Since you know the perimeter, you can plug it in.(you could have also plugged it in in the beginning)
P = 4x + 9
14 = 4x + 9 Subtract 9 on both sides
5 = 4x Divide 4 on both sides
5/4 = x
Now that you know x, find the side length of the square.
(x + 2 1/4)
(5/4 + 2 1/4)
2 6/4 = 3 2/4 = 3 1/2 units or 3.5 units
To find the area of a square, you multiply 2 of the sides together:
A = s · s
A = 3.5 · 3.5
A = 12.25 units²
I'd say angle A = angle B
arc tangent (angle B) = 150 / 555

angle B = 15.124 degrees
By the way 555 feet is the height of the Washington Monument.
