Answer:
x = 63
Step-by-step explanation:
x + 2 + 25 = 90
x + 27 = 90
x = 63
I hope that helps.
The correct answer is D.
The graph shows the set of values that y takes, so you can see that the thick black line goes from -2 to 3 and the black point at -2 represents a closed interval at this point and the empty point at 3 represents an open interval at that point.

Dilation involves changing the size of a shape
<h3>How to determine the relationship between the trigonometry ratios</h3>
From the question, we understand that:
The dilation of triangle XYZ gives triangle ACB
This means that, the following are corresponding points
- Points X and A
- Points Y and C
- Points Z and B
The above means that:
The relationships between the trigonometry ratios of both triangles are:
cos(X) = cos(A), cos(Y) = cos(C) and cos(Z) = cos(B)
<h3>How to determine the measures of segments AC and AB</h3>
In (a), segments XY and XZ corresponds to the segments AC and AB
So, the product of the lengths of XY and XZ and the scale factor will result in the lengths of AC and AB,
i.e.
AC = 2 * XY and AB = 2 * XZ

Its an indirect proof, so 3 steps :-
1) you start with the opposite of wat u need to prove
2) arrive at a contradiction
3) concludeReport · 29/6/2015261
since you wanto prove 'diagonals of a parallelogram bisect each other', you start wid the opposite of above statement, like below :- step1 : Since we want to prove 'diagonals of a parallelogram bisect each other', lets start by assuming the opposite, that the diagonals of parallelogram dont bisect each other.Report · 29/6/2015261
Since, we assumed that the diagonals dont bisect each other,
OC≠OA
OD≠OBReport · 29/6/2015261
Since, OC≠OA, △OAD is not congruent to △OCBReport · 29/6/2015261
∠AOD≅∠BOC as they are vertical angles,
∠OAD≅∠OCB they are alternate interior angles
AD≅BC, by definition of parallelogram
so, by AAS, △OAD is congruent to △OCBReport · 29/6/2015261
But, thats a contradiction as we have previously established that those triangles are congruentReport · 29/6/2015261
step3 :
since we arrived at a contradiction, our assumption is wrong. so, the opposite of our assumption must be correct. so diagonals of parallelogram bisect each other.
