Answer:
y = 7
Step-by-step explanation:
An equilateral triangle has all its sides to be equal..
so.
10 = x
10 = y + 3
y = 10 - 3
y = 7
That my dear your answer would be 16 degrees hope this helped
The area of the shaded region can be found by subtracting the area of the inside rectangle from the outside rectangle
area of outside: 6 X 10y —> 60y
area of inside: 3 X 5x —> 15x
so the area of the shaded region is 60y-15x
the GCF is 15, so the factored form is: 15(4y-x)
Answer: other than 7
Step-by-step explanation:
Given
Equation is 
For an equation to have no solution, the missing number can be any number other than 7
because if we put 7 then it justifies the equation i.e.
while on the other hand for a number other than 7, it does not justify the equation.
