The polar equation is r = 2 + cos(theta).
Given,
A choir is performing in front of an audience. a microphone is placed in front of the choir to capture sound.
The polar equation represents the microphone the choir is using i.e
On edge i.e r = 2 + cos(theta)
Hence, The polar equation is r = 2 + cos(theta).

Step-by-step explanation:
36A) AB = 4/ sin 30° = 4/ 0.5 = 8 cm
36B) AC = 4/ tan 30° = 4/ 0.577 = 6.9 cm
36C) BD = 4/sin 45° = 4/ 0.707 = 5.7 cm
36D) area of ∆ABC = ½×6.9×4= 13.8 cm²
36E) sin A = sin 30° = 0.5
That would be
10x > 4x - 2
Well since the triangle is right angled you know that the given angles sum to 90........(angle sum of a triangle 180, 1 angle = 90) so you can say 3x + 6 + 2x - 1 = 90 or 5x - 5 = 90 now solve for x. the smaller angle will be 2x - 1 so substitute your answer for x and you'll have the measure of the smaller angle. hope that helps
I think the answer for this is H
