Answer: 
<u>Step-by-step explanation:</u>


Insert x = 13 and y = 1:
x² + 2hxy + 12y² = 0
(13)² + 2(13)(1) + 12(1)² = 0
169 + 26h + 12 = 0
26h + 181 = 0
26h = -181




Answer:
X<_200
Step-by-step explanation:
We know that if the number connot be more than 200 then the number is less than or equal to 200
<u>Given</u>:
Given that the angles of the kite.
The opposite angles of the kite measures (3y + 14)° and (y + 50)°
We need to determine the value of y.
<u>Value of y:</u>
We know the property that the opposite angles are equal.
Thus, applying the property, we have;

Subtracting both sides of the equation by y, we have;

Subtracting both sides of the equation by 14, we get;

Dividing both sides of the equation by 2, we get;

Thus, the value of y is 18.

Answer
D.
Explanation
mIH = 44
mIJ = 46
mJK = 77
ADDING THEM ALL TO FIND THE MEASURE OF m<HOK
<HOK = 44+46+77
<HOK = 167°
