Answer:
x=9
adjacent angles
Step-by-step explanation:
we can set up an equation because if we add these angles, we will get our 90 degree angle,
lets solve for x, first add like terms,
9x+9=90, subtract 9 from both sides, 9x+9-9=90-9, 9x=81
divide both sides by 9 and we get 9, so x=9
These are adjacent angles because adjacent angles are angles that are right next to each other. They can form a bigger angle because they are right next to each other
Answer:
Step-by-step explanation:
Given the equation
Step 1;
Expand the bracket at the right hand side of the equation to have:
Taking the reciprocal of both sides:
Answer:
The volume of the tumor experimented a decrease of 54.34 percent.
Step-by-step explanation:
Let suppose that tumor has an spherical geometry, whose volume () is calculated by:
Where is the radius of the tumor.
The percentage decrease in the volume of the tumor () is expressed by:
Where:
- Absolute decrease in the volume of the tumor.
- Initial volume of the tumor.
The absolute decrease in the volume of the tumor is:
The percentage decrease is finally simplified:
Given that and
, the percentage decrease in the volume of tumor is:
The volume of the tumor experimented a decrease of 54.34 percent.
