Answer:
b
Step-by-step explanation:
Using the trigonometric identities
cot x =
and tan x =
thus
+ tanΘ × cosΘ
=
+
× cosΘ
= cosΘ ×
+ sinΘ
= sinΘ + sinΘ
= 2sinΘ → b
Answer:
7
Step-by-step explanation:
2b - 5b is -3b so it leaves the equation with -3b + 7 + 3b
-3b + 3b cancells out to 0 so it leaves the final answer to 7
