Convert 72° 36' 45" into centesimal measurement.​
zavuch27 [327]

Answer:

Answer:

8

Step-by-step explanation:

x= centesimal angle (100 degrees in a

right angle)

y= sexagesimal angle (90 degrees in a

right angle)

=

x - y = 15

xx90/100 = y

xx9/10 = y

X - XX9/10 = 15

10x/10 - 9x/10 = 15

=

X/10 = 15

x= 150

y = 150x9/10 = 15x9 = 135

=

using centesimal system:

the sum of all external angles in a

polygon is 400 degrees (a full circle).

one external angle is the complement

of one internal angle to 200 degrees =

200-150=50 degrees.

to find the number of sides of the

polygon we need to find the number of

angles or corners. and that is how many

external angles fit into the full circle.

n = 400/50 = 8

=

the polygon has 8 sides

2 tangents are drawn from a point a which is 37 cm from the center of the circle. The diameter of the circle is 24 cm. What is t
kipiarov [429]

Answer: 35 cm

Step-by-step explanation:

Given : Diameter of a circle= 24 cm

Let r be the radius of the circle.

then r=\frac{d}{2}=12\ cm

Since a tangent is always at right angles to the radius where it touches the circle.

Join the point A to the center of the circle such that it will become a right triangle with 37 cm as the longest sides [since it is the side opposite to the right angle.]

Let x denote the length of the tangents.

By Pythagoras theorem, we have

r^2+x^2=(37)^2\\\Rightarrow\ (12)^2+x^2=1369\\\Rightarrow\ x^2=1369-144\\\Rightarrow\ x^2=1225\\\Rightarrow\ x=35

Hence, the length of each tangent from point a to the point of the tangency=35 cm
