Answer:
30 degrees.
Step-by-step explanation:
Let the acute angle be x.
Then as the 2 acute angles in a right triangle sum to 90 degrees,
x = 90 - 60
= 30.

Step-by-step explanation:
<u>GCF= Greatest Common Factor</u>
Given a polynomial, the GCF is the largest polynomial that will divide evenly into that polynomial.
The polynomial is

First, we find the GCF of the coefficients:
16, 32, 48
Since 32 and 48 are multiples of 16, 16 is the GCF of the coefficients.
Now we select all the repeating variables with their smallest exponent:


The GCF of the polynomial is

Answer:
Step-by-step explanation:
Given
diameter of pie is 
radius 
If child divides pie into 12 equal parts then each part subtends an angle of
at the center
and crust length of single piece is



For two slice length is 
Thus the total length of crust eaten is
