Answer:
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
10*y-(80)=0
Pull out like factors :
10y - 80 = 10 • (y - 8)
Solve : 10 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : y-8 = 0
Add 8 to both sides of the equation :
y = 8
The answer is
(0,0)
Goodluck
Answer:
13.9 inches
Step-by-step explanation:
Let the length of diagonal of cube be d inches.

If 30 60 90 right triangle then ratio of short leg : long leg : hypotenuse = a : a√3 : 2a
in this case
short leg = 4
long leg = 4√3 (short leg times √3)
and
hypotenuse = 8 (twice of short leg)
so answer is A.
The angle measures are 30, 60 and 90
The answer to the question is B.14 because 3 + 5 + 6
