Solution :
We know, cot 2θ = 1/tan 2θ
Multiplying tan 2θ both side of the given equation.
tan²2θ - 3tan 2θ - 10 = 0
tan²2θ - 5tan 2θ + 2tan 2θ - 10 = 0
tan 2θ ( tan 2θ - 5 ) + 2 ( tan 2θ - 5 ) = 0
tan 2θ = -2 or tan 2θ = 5
Therefore, or
Hence, this is the required solution.
Answer and Step-by-step explanation:
2.
The value of x is equal to 148. This is because of the vertical angles theorem.
The vertical angles theorem states that when two angles are vertical to each other (such as the example in this problem), then they are equal to each other.
5.
We know that a line has a angle of 180 degrees. So, to find x, we subtract everything from 180.
180 - 125 - 30 = x
25 = x
8.
We know that given angle in total is equal to 89 degrees. So, to find x, we subtract everything from 89.
89 - 12 - 29 = x
48 = x

Answer:
3
Step-by-step explanation:
Given the question :
The value of n is a distance of 3 units from 1 an 1/2 on a number line click on the number line to the possible values of n
From the context of the expression:
n is the distance which exists between 1 1/2 and 3 units from it;
Which may be ;
1 1/2 - - - - (1 1/2 + 3) = 4 1/2
1 1/2 - - - - - (3 - 1 1/2)
Either way, there exists a distance of 3 units between 1 1/2 and 3 units from it.
Hence, n = 3
It is D because it means supplementary angles which equal up to 180
