Step-by-step explanation:
8x - 9y = 11
8x = 9y + 11
8x - 11 = 9y
y = 8x/9 - 11/9
so, C is correct
Answer:
Step-by-step explanation:
1. Corresponding Angles
<1 and <5
<2 and <6
<3 and <7
<4 and <8
They are equal in measure because corresponding angles are always equal to each other which means that they are congruent.
2. Alternate Interior Angles
<3 and <6
<4 and <5
They are always equal to each other because alternate interior angles are always congruent.
3. They are alternate exterior angles which means that the angles are always congruent.
4. <8 will be 73 degrees which is the same as <4 because they are corresponding angles and they are always congruent.
5. Angle 6 will be 107 degrees because they are alternate interior angles and they are always congruent.
I think r is 1/2 but is not in the option
Answer:
The new water level decreased by 0.8 centimeters compared to the original water.
Step-by-step explanation:
Change = (-1.9) + 3.5 -2.4
= (-0.8)
Obtuse because it only takes one obtuse angle to make an obtuse triangle
