Answer: 60
Step-by-step explanation:
Almost everything in this picture is irrelevant to finding the measure of x.
x = 180 - 90 - 30 = 60
Answer:
pqr
Step-by-step explanation:
By applying the formula of trigonometric function the right hand side will
be equal to right hand side which is 1-
/
=cos2x.
Given: 1-
/
=cos2x.
Taking right hand side first which is cos2x.
We know that cos2x=
Now we will solve the left hand side of the equation give which is
1-
/
=1-
/1+
[secant square x minus tangent square x is equal to 1]
By putting both values left hand side and right hand side we will find our solution which is :
1-tan^{2}x/1+tan^{2}x=1-
/1+
.
Hence proved
