Answer:
cos(400)
Step-by-step explanation:
Useful things:
Cofunction identity: sin(x)=cos(90-x)
Sine and cosine have period of 360 degrees.
So sin(50)=cos(40) by cofunction identity.
Since cosine has period of 360 degrees then cos(40)=cos(360+40).
That simplifies to cos(400).
Tan6.5=h/4
h=4tan6.5 mi
h≈0.5 mi. (to nearest tenth of a mile)
Answer:
D
Step-by-step explanation:
XY= 58+64 which is 122
WY= 55+64 which is 119
122 (XY) is more than 119 (WY)
