Answer:
Step-by-step explanation:
sin²β + sin²β×tan²β = tan²β
sin²β( 1 + tan²β ) = tan²β
~~~~~~~~~~~~~~~~
<u><em>sin²β + cos²β = 1 </em></u>
<u><em /></u>
+
=
⇒ tan²β + 1 = sec²β ⇔ 1 + tan²β = sec²β
~~~~~~~~~~~~~~
1 + tan²β =
L.H. = sin²β (
) = tan²β
R.H. = tan²β
The right answer is -2/3

Answer:
N = 140
Step-by-step explanation:
N/7 = 20
Inverse operation of division: multiplication
N/7 = 20
becomes:
N = 7 x 20
N = 140
Thus, the value of N is 140.
