Which is the approximate measure of this angle A. 30 b. 90 c 120 d 180
statuscvo [17]

Answer:

Answer is A. 30 degree

as we know that two prependicular lines have 90 degree angle between them

and similarly a horizontal line has angle zero degree.

the angle of pic shown is approximately 30 degree as it lies between prependicular and horizontal nature of lines

but as we can see that it is close to horizontal nature of the line that's why its approximate angle is 30 degree.

Consider circle C with radius 5 cm and a central angle measure of 60°. What fraction of the whole circle is arc RS?
skelet666 [1.2K]

Answer:

There are a total of 360° in any given circle, so an arc swept out by 60° of that 360° would make up 60/360 = 1/6 of the circle's circumference.

The formal for the circumference of a circle comes out of the definition of one of the most famous constants in mathematics: π. π is defined as the ratio between a circle's circumference and its diameter, or:

From this definition, we can multiply both sides of the equation by d to obtain

or, circumference is π times the diameter. To find the diameter, we just need to double the radius, giving us 5 * 2 = 10cm. Usually you'll see π approximated as 3.14, which is likely what they want you to use here. Using that approximation, we find the circumference to be 3.14 * 10 = 31.4 cm.

Finally, to get the length of that arc, we just need to take 1/6 of the circumference (since the arc sweeps out 1/6 of the circle), giving us 31.4 * 1/6 ≈ 5.2 cm.

Keiko, aldo, and henry sent a total of 50 text messages during the weekend. aldo sent 2 times as many messages as henry. keiko s
Lady_Fox [76]
K + a + h = 50
a = 2h
k = h - 10

(h - 10) + 2h + h = 50
4h - 10 = 50
4h = 50 + 10
4h = 60
h = 60/4
h = 15 <=== Henry sent 15

a = 2h
a = 2(15)
a = 30 <=== Aldo sent 30

k = h - 10
k = 15 - 10
k = 5 <=== Keiko sent 5
