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.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
