Answer:
Step-by-step explanation:
Answer:
there were 200 children and 500 adults at the show
Step-by-step explanation:
7x+10y=6400
x+y=700
x=700-y
7(700-y)+10y=6400
4900-7y+10y=6400
-7y+10y=1500
3y=1500
y=500
x=700-y
x=700-500
x=200
Answer:
Short leg = 10
Longer leg = 10
Hypotenuse = 20
Step-by-step explanation:
The given is a special right triangle, its angle measures are as follows:
30-60-90 and the side lengths will follow as:
x, x, 2x respectively.
The length of hypotenuse (sees angle measure 90) is represented with 2x and it's given as 20
We can conclude x = 10 from this
So the length of short leg is 10
Then the length of longer leg is 10
The length of hypotenuse is already given as 20
