Your question is missing some words and cannot be answered as asked.
However, it seems that the question is simply testing your knowledge of the term "vertical angles." Vertical angles are equal to each other. So if F and D are vertical angles, and one of them is 53°, then the other one is 53° as well.
But again, would need the full question to be sure.
Answer:

Step-by-step explanation:
The nth term of the sequence is

To get the first term, substitute n=1,

To get the second term, substitute n=2,

To get the third term, substitute n=3,

The sum of the first three terms is

We could also use the formula
to get the same result.
Answer:
97,99,101,103
Step-by-step explanation:
Let x = first odd integer
x+2 = 2nd odd integer
x+4 = 3rd odd integer
x+6 = 4th odd integer
Sum of 4 odd integers is 400
x+ (x+2) + (x+4)+(x+6) = 400
Combine like terms
4x +12 = 400
Subtract 12 from each side
4x+12-12 = 400-12
4x = 388
Divide by 4 on each side
4x/4 = 388/4
x=97
The first integer is 97
The 2nd is 97+2 =99
The third ix 97+4 = 101
The 4th is 97+6 = 103
Hello!
If our answer is in scientific notation, our answer will be multiplied by 10 to a power. In this case, we will only need to multiply 8 by 8.8.
This gives us 70.4(10^12).
I hope this helps!
Answer:
1.047 ft
Step-by-step explanation:
The length of an arc is given by ...
s = rθ
where s is the arc length, r is the radius, and θ is the central angle in radians. Your arc subtends an angle of 12° = (12·π/180) = π/15 radians. The length of the arc is then ...
s = (5 ft)(π/15) = π/3 ft ≈ 1.047 ft
