Answer:

Incentre

Step-by-step explanation:

A triangle is a closed area in a plane bounded by three lines known as sides of a triangle.

There will be 3 angles in a triangle.

Consider the point of concurrency of three bisectors.

Let ABC be one triangle and AI and BI are bisectors of A and B meeting at I.

Then we have since AI is angle bisector of A, I would be equidistant from sides BA and AC. Similarly since BI is angle bisector of B, I would be equidistant form BC and BA.

It follows that I is equidistant from all the sides, and hence a centre can be drawn touching all sides of the triangle.

The circle is called in circle and the point I, the point of concurrency of the angle bisectors of a triangle, is the incentre of the triangle.

The given speed in kilometers per sec to miles per hour is 51449.534 mph.

Given that, the Oyo Empire if they are traveling 23 kilometers per sec.

<h3>What is the speed?</h3>

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Now, the conversion of kilometers per sec to miles per hour is as follows:

To convert a kilometer per second measurement to a mile per hour measurement, divide the speed by the conversion ratio.

Thus, mph = km/s ÷ 0.00044704

Now, 23/0.00044704

= 51449.534 miles per hour

Hence, the given speed in kilometers per sec to miles per hour is 51449.534 mph.

slamgirl [31]

Answer:

20% increase

Step-by-step explanation:

All you have to do is divide 72 by 90n and it will give you .8, move the decimal two places to the right to give you 80 and subtract 80 from 100 to get 20

Answer:

Horizontal distance between lifeguard and the person is 22 feet.

Step-by-step explanation:

Given: A lifeguard sees a person in distress.The eye level of the lifeguard is 15 feet above the ground. Angle of depression is 34°.

To find: Horizontal distance between lifeguard and the person.

Solution : If we draw a triangle then tan∅ = $\frac{height}{base}$
