It would be best if you draw or sketch the system described above. You will see that a right triangle would be formed where the height of the triangle is equal to the height of the tower and the base would be equal to the shadow casted by the tower. We can use a trigonometric function for this.
tan (angle) = height / base
angle = tan^-1 (height /base )
angle = tan^-1 (154 /166 )
angle = 42.85 degrees
Answer:
12
Step-by-step explanation:
it’s 12 because 4 x 3 = 12
Answer:
2 hours
Step-by-step explanation:
I substituted y for 126 and solved like so:
126 = 38x + 50
126 - 38x = 50
(126-126) - 38x = 50 - 126
-38x = -76
-38x/-38 = -76/-38
X = 2
There ya go! Hope this helps, good luck :)
Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.
Answer:
n = -32
Step-by-step explanation:
quotient means divide
n/-4 = 8
Multiply each side by -4
n/-4 *-4 = 8*-4
n = -32
