Answer:
The measure of arc EF = 41°
Step-by-step explanation:
Given:
Arc DE = 73°

Now, we know from central angle theorem that the measure of central angle by an arc is twice that of the angle made by the same arc at the circumference. Therefore,

Now, we know that sum of all arcs on a circle is equal to 360°.
Therefore, arc DGF + arc DE + arc EF = 360°

Therefore, the measure of the arc EF is 41°.
Answer:
144
<h3>
Step-by-step explanation:</h3>
If 48 is the perimeter, then 48 divided by 4 is one of the side lengths.
L x W = Area
12 x 12 = Area
12 x 12 = 144
Area = 144
7: the answer is C because 3/4 divided by 2/3 equals 1 1/8 and C if you multiply 3/4 x 3/2 it equals 1 1/8
14: the answer is 18 because if you add all the numbers they picked you’ll get 6 then divide it by 1/3 you’ll get 18
Then the other 2 km not sure I’m sorry
