Answer:
14
Step-by-step explanation:
Sin(∅) = Opposite angle ÷ hypotenuse.
Sin (45) = 7
÷ hypotenuse
hypotenuse = 7 ÷ sin(45)
*********************
Keep in mind
sin(45) = √2÷2
*********************
so we have: Hypotenuse = 7√2 ÷ (√2÷2)
Hypotenuse= 14.
Answer:
An even number: 1/2, A multiple of 3: 1/4, A multiple of 4: 1/4, Not a multiple of 4: 3/4, Less then 4: 3/8
Step-by-step explanation:
Since there are eight faces all you have to do is take the number that answers the question and put it over eight.
Answer:
x = 5, y = 3
Step-by-step explanation:
<u>Elimination method: (I will be eliminating 4y) </u>
3x + 4y = 27 --- Equation 1
x + 4y = 17 --- Equation 2
Equation 1-2: 3x + 4y - x - 4y = 27 - 17
2x = 10
x = 10 ÷ 2
x = 5
Substitute x = 5 into Equation 2:
x + 4y = 17
4y + 5 = 17
4y = 17 - 5
= 12
y = 12 ÷ 4
y = 3
