If a angle on the circumference of a circle is subtended by a diameter of the circle what is the angle
Brilliant_brown [7]

Answer:

The angle is 90 degrees

Step-by-step explanation:

Required

Angle subtended by the diameter

The theorem to solve this is:

The angle subtended by an arc is twice the angle it subtends.

<em></em>

<em>The diameter forms </em>180^\circ<em> on the circle, so we have:</em>

<em></em>2*\theta = 180^\circ<em></em>

<em></em>

Where \theta is the angle subtended

Solve for \thets\theta

<em></em>\theta = \frac{180^\circ}{2}<em></em>

<em></em>\theta = 90^\circ<em></em>

Two old RSM students were standing ten feet apart when they ran in opposite directions with speeds of 180 feet per minute and 16
inessss [21]

The number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

  • Since one student runs at a speed of 180 feet per minutes, in time t minutes, he moves a distance of d = 180t.
  • Also, the second student runs at a speed of 160 feet per minute, in time t minutes, he moves a distance of d' = 160t.

Since they are initially 10 feet apart, their total distance apart after t minutes is D = d + 10 + d'

D = 180t + 10 + 160t

D = 340t + 10

<h3>Number of minutes before they are 1870 feet</h3>

Making t subject of the formula, we have

t = (D - 10)/340

Since they are 1870 feet apart after t minutes, D = 1870 feet.

t = (D - 10)/340

t = (1870 - 10)/340

t = 1860/340

t = 5.47 minutes

So, the number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

tangare [24]

Answer:

A - They Have Too Much Caramel
