This is the concept of trigonometry, the value of x will be calculated as follows;
sin theta=[opposite]/[hypotenuse]
theta=x
opposite=16 units
hypotenuse=21 units
thus;
sin x=16/21
hence;
x=arcsin(16/21)
x=49.63
x=50 (to the nearest degrees)

Answer: 46 pounds</h3>
===============================================
Work Shown:
N = weight of Noah's dog = 15 & 1/3 pounds
A = weight of Aiden's dog = unknown
A = 3*N
A = 3*(15 & 1/3)
A = 3*(15 + 1/3)
A = 3*15 + 3*(1/3) .... distribute
A = 45 + 1
A = 46
Aiden's dog weighs 46 pounds.
Answer:
So for this problem, we can use the formular:
(A + B)² = A² + 2AB + B²
Our orginal expression is: (x + 4)². In this expression, A can be written as x, B represents for 4, that leads to our answer:
(x + 4)² = x² + 2 . 4x + 4² = x² + 8x + 16
The correct answer will be D
I think it’s c because it look a
