The quotient of 120 and 60 is 120/60, which is 2. the quotient of 72 and 9 is 72/9, which is 8. 2 + 8 = 10, so the answer is 10
Answer:
5√3
Step-by-step explanation:
The ratio of side lengths in a 30-60-90 triangle is ...
1 : √3 : 2
__
Multiplying by 5, we have ...
1 : √3 : 2 = x : y : 10 = 5 : 5√3 : 10
The value of y is 5√3.
_____
<em>Additional comment</em>
y is the side adjacent to the 30° angle, so can be found from ...
Cos = Adjacent/Hypotenuse
Adjacent = Cos × Hypotenuse . . . . . multiply by hypotenuse
y = cos(30°)×10 = (√3)/2 × 10 . . . . . . substitute corresponding values
y = 5√3
__
The value of x is 5.

Answer:
Step-by-step explanation:
Jonah sister is 10 years old. Jonah is 8 years younger than twice hos sister age
j = 2s - 8
this is the equation.
You can solve it by substituting in 10 for s, because sister is 10 years old.
The answer is B. That is not a valid way to sample as it is not randomly selected.
