Answer:
D
Step-by-step explanation:
Replace R1 with 1 and R3 with 0 you have -2(1)+0 which equals 0 and that matches matrix II. Repeat the process with the other numbers in R1 and R3 and they all come out equal therefor the answer is D.
Answer:
23 degrees
Step-by-step explanation:
62+95=157
180-157=23
The answer is 3√5. You use the distance formula: √((x2-x1)^2+(y2-y1)^2)

Answer:
The measure of the sum of interior angles of a 11-gon is
.
Each interior angle is approximately
.
Step-by-step explanation:
A convex polygon has the measure of each interior angles to be less than
.
But,
sum of interior angles of polygon = (n - 2) x 
where n is the number of sides of the polygon.
For a convex 11-gon, we have;
sum of angles of a 11-gon = (11 - 2) x 
= 9 x 
= 
Sum of angles of a 11-gon = 
To check: convex polygons' interior angles are less than
.
so that,
each interior angle of 11-gon = 
=
