Find the area of one petal of the polar curve r = 3 cos 3 θ. A. 7π / 12
B. 3π/ 4
C. 11π / 12
D. 2π

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

hi there, i would be interested to you with your test, may you add the questions and answer options.

1,2,4,5,10,11,20,22,44,55,110,220

triangle eg 7.5 × cos "a" or 7.5 × sin "b" or 6 tan"a"
