Answer:
the correct answer is A good luck
Step-by-step explanation:
Answer:
Q = 40.6°
Explanation:
Given three sides: 9.6, 8.1, 6.3
Use the cosine rule:
c² = a² + b² - 2ab cos(C)
Insert following variables:
6.3² = 9.6² + 8.1² - 2(9.6)(8.1) cos(Q)
39.69 = 157.77 - 155.52 cos(Q)
cos(Q) = -118.08/-155.52
cos(Q) = 41/54
Q = cos⁻¹(41/54) = 40.6°
17. 187 divided by 11 equals 17.
You use Sin-Cos-Tan. Since Tan is opposite and adjacent (SOH-CAH-TOA) we use that equations which is listed below. We rearranged the equation to get O alone and then plug everything in.
Answer:
Option a 
Step-by-step explanation:
we know that
The equation of a circle in standard form is

where
(h,k) is the center of the circle
r is the radius
In this problem we have

substitute in the equation
