Answer:
y = 70 and x = 20
Step-by-step explanation:
180 - 40 = 140
140/2 = 70
70 + 90 = 160
180 - 160 = 20
Answer:
Step-by-step explanation:
(-5,-3) is a point on the graph.
f⁻¹(-3) = -5
Answer:
C° = 71.6056
Step-by-step explanation:
Law of Cosines: c² = a² + b² - 2abcosC°
Step 1: Plug in known variables
29² = 30² + 15² - 2(30)(15)cosC°
Step 2: Evaluate
841 = 900 + 225 - 900cosC°
-59 = 225 - 900cosC°
-284 = -900cosC°
71/225 = cosC°
cos⁻¹(71/225) = C°
C° = 71.6056
And we have our answer!
The answer is: cosV=39/89=0,43
