Answer:
90°, 270°
Step-by-step explanation:
2r sin(Ф/2) = c
2r sin (Ф/2) = √2r
divide both sides by 2r
sin (Ф/2) = √2r/2r
sin(Ф/2) = √2/2
From the unit circle sin is √2/2 at 45°, and 135°
so Ф/2 = 45
Ф=90°
and Ф/2 = 135
Ф= 270°
Answer:
-32°F
Step-by-step explanation:
current temperature = -20°F-12°F
= - 32°F
I am not sure if its correct
I am not sure but wouldn't it be y=3x-6 and y=4x-7
