Answer:
Step-by-step explanation:
You know the linear pair z° and 105° are supplementary angles, so ...
z = 180 -105 = 75
The other base angle of the isosceles triangle has the same measure, 75°. __
Then x can be found either from the sum of interior angles of the triangle, or from the relation of 105° to the "remote interior angles". The first relation gives ...
75° +75° +x° = 180° ⇒ x = 180 -150 = 30
The second relation gives ...
75° +x° = 105° ⇒ x = 105 -75 = 30
__
y° is supplementary to the left-side base angle, so is ...
y = 180 -75 = 105
Of course, you could also figure y from the symmetry of the figure.
The values of x, y, z are 30, 105, 75, respectively.
I think maybe 3) would make the most sense because she wants a random sample of students and the other options are specific on the type of students.
It’ll be C or B with no soul took by finding the value.
Hello there.
To answer this question, we need to remember some properties about the vertex of quadratic functions.
Let 
. Its vertex can be found on the coordinates 
such that 
and 
, in which 
.
Using the coefficients given by the question, we get that:
Thus, we have:
So the statement is true, because the 
coordinate of the vertex of the function is equal to 
Answer: 
if you want 3/6 in simplifed form it will be 1/2
