You cannot have an answer to this because it is not an equation
Answer:
Since 81° is less than 90, we can express this in terms of a cofunction. sin(θ) = cos(90 - θ) sin(81) = cos(90 - 81) sin(81) = cos(9)
Step-by-step explanation:
Answer:
The sum of the other 4 numbers is 
Step-by-step explanation:
Let
x------> the sum of 6 numbers
y-----> the sum of the other 4 numbers
we know that
-----> equation A

substitute the value of x in the equation A






The answer would be B. 4,365,205. Hope I helped!
Answer:
Acute
Step-by-step explanation:
Note the definitions:
Obtuse: At least one of the angles are greater than 90°
Equilateral: All angles are congruent & equal to 60°
Acute: All angles are less than 90°
Right: At least one angle is equal to 90°
In this case, the triangle is a D) acute, for it fits the requirement for being an acute... all angles are less than 90°.
