The answer is -13. You figure it out by multiplying 2.5×-5.2=13
Sin74 = Cos16
cause 16 + 74 = 90
Whenever the sum of two angles is equal with 90, the Sin of one is equal with the Cos of the other like :
Sin(30) = Cos(60)
and also
Tan(30) = Cot(60)
The area is 3.14*r^2
<span>The rotating valve would be in the center of the circular wet patch so if it's spraying in all directions, then 15 ft = radius. </span>
<span>Now plug it in. </span>
<span>3.14 x (15)^2 = 706.5 ft^2</span>
Step-by-step explanation:
for triangle HLM
180-2x
180-(3x+6)
H
2x=3x-10
x=10°
180-36=144°
36-20=16°
H=2x
H= 180-144-16= 20°
