Cot x = cos x / sin x
cot π/4 = cot 45° = cos 45° / sin 45°
We know that sin 45° and sin 45° have the same value:
cos 45° = sin 45° = √2 / 2;
cos 45° / sin 45° = √2/2 : √2/2 = 1
Answer:
cot π/4 = 1
Answer:
432
Step-by-step explanation:
2250x4.8=10,800
5x5=25
10,800/25=432
Answer:
<VUT = 50
Step-by-step explanation:
Tangent Chord Angle = 1/2 Intercepted Arc
< VUT = 1/2 (100)
<VUT = 50
Answer:
Area of bigger rectangle = length x breadth = 12 x 9 = 108 square cm
Area of small rectangle = length x breadth = 8 x 5 = 40 square cm
Area of the shaded region = Area of big rectangle - Area of small rectangle
= 108 - 40 = 68 square cm
That is false, 70 / 4 is not 17 mph
it is 17.5 mph
