Given: ∠JNL and ∠MNK are vertical angles and m∠MNK=90°
Prove: ∠JNL is a right angle.
Statements Reasons
1. ∠JNL and ∠MNK are vertical angles. Given
2. 
Vertical angle theorem
3. 
Angle congruence postulate
4. 
Given
5. 
<u> Substitution Property of Equality</u>
Since, the measures of angle JNL and MNK are equal and the measure of angle MNK is 90 degrees. therefore, by substitution property of equality, both the angles JNL and MNK will have an equal measure.
Therefore,
6. ∠JNL is a right angle. Definition of right angle
It has already given you the answer.
Answer:
xy=8
Step-by-step explanation:
The equation for inverse variation is
xy = k where k is the constant of variation
4*2 = k
8=k
The equation is
xy=8

Answer:
The volume of the rectangular prism is 880 u³
Step-by-step explanation:
To calculate the volume of a rectangular prism we have to use the following formula:
v = volume
w = width = 11 units
l = length = 8 units
h = height = 10 units
v = w * h * l
we replace the values that we know
v = 11u * 10u * 8u
v = 880 u³
The volume of the rectangular prism is 880 u³
