Answer:
42.602 cm
Step-by-step explanation:
<O =360/5=72°
sin <O =sin 72 = opp/adj = TA / 7
TA = 6.66 cm
Area of ABT = 7*6.66 = 42.602 cm
Answer:
Distance between the observer and the red car is
Step-by-step explanation:
Diameter of field = 500 m
Radius of field =
Let R be the radius and the speed at which the car completes race be w
So,
Car finished 5 laps in minutes = 30
Car finished 1 lap in minutes =
So,
Refer the attached figure
Angle between car and observer = wt
So, Distance between the observer and the red car is give as A sin wt
So, Distance between the observer and the red car=
The next one would be that teal color (circle) and then the square would be purple
14 x 12 = 168
168 divded by 2.90 = 57.9
Answer:
x = 5.4
Step-by-step explanation:
The marked sides are the hypotenuse and the side adjacent to the marked angle. That suggests the appropriate trig function is the cosine:
Cos = Adjacent/Hypotenuse
cos(19°) = 5.1/x
x = 5.1/cos(19°) . . . . . multiply by x/cos(19°)
x ≈ 5.4
