Answer:
The value of is .
Step-by-step explanation:
The given equation is
We need to find the value of .
Differentiate with respect to t.
It is given that y=2 and dy/dt=1, substitute these values in the above equation.
Divide both sides by 4x³.
Therefore the value of is .
Since vertical angles are equal you can put the same value to the opposite angles. Also, you were given a supplementary angle which are two angles added to 180 degrees. Of those 180 you were given 100. The angle next to the 100 degrees has a value of 80. With all this, you add all the angles together and put it equal to 180 which is what the angles of a triangle add up to. Then you combine like terms to get the value of X and just replace it for x. After that you just multiply and then add.
Answer:
Option D
Step-by-step explanation:
a^2 + b^2 = c^2
5^2+b^2=9^2
25+b^2=81
b^2=56
b=2√14
