Answer:
C (-2, 0)
Step-by-step explanation:
y = x+2
intersect the x-axis when y = 0, then
0 = x+2
x = -2

Answer:
B) identity property of addition.
Step-by-step explanation:
Given:
The statement given is:

Here, we observe that 10 is added to a giving the number 10 itself as the answer. So, we know of a property which says that when 0 is added to a number, the result is the number itself. This property is called identity property of addition.
So, the value of  must be 0 because on adding
 must be 0 because on adding  to 10, we are getting the number 10 only. So, the above statement is an example of identity property of addition.
 to 10, we are getting the number 10 only. So, the above statement is an example of identity property of addition.
 
        
             
        
        
        
Answer:
D. 60, 45,75
Step-by-step explanation:
For options C and D
For a triangle the sum of the angles must always be equal to 180 degrees
So 180 ≠45+45+80
and 
 60 +45+ 75= 180
For option A and B
The length of the longer side is equal to the square root of the sum of squares of the other two sides in a triangle.
According to Pythagorus theorem 
hypotenuse²= base² + perpendicular²
c²= a²+ b²
90²= 50² + 35²
8100= 2500+1225
8100≠3725
95²= 60²+ 25²
9025= 3600+ 625
9025≠4225
Therefore only D is the correct option
