What type of angle is 45 degrees???

Acute angle

Step-by-step explanation:

45°= Acute Angle

‘Cause It's less than 90°

Step-by-step explanation:

It's an acute angle. Acute, in this case, means anything between 0 and 90 written 0<x<90. Notice that you are using < and not ≤. The endpoints are not included. They have their own names. 90 is a right angle. 0 is called a zero degree angle.

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
