10) 5

11) Scalene

Step-by-step explanation:

10) A regular hexagon has equal sides, so one side is just 30/6, which is 5 feet.

11) A scalene triangle has no two sides that are the same length, where an isosceles triangle has two sides the same, and an equilateral triangle has all sides the same length.  

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

because that’s us why
