What is the measure of arc ef in circle h?
o 41°
o 50°
o 114
o 1730

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°.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
