C

Step-by-step explanation:

You can use elimination by plugging in choices, by the time I get to C you know that 2/1+3/3=3 and that 3/1+6/3=5

The answer is C.

Step-by-step explanation:

First you have to solve this simultaneous equation by substitution :

Next you can make any variable as a subject. So I will choose to make x the subject in (1) :

Lastly, you can solve the equations :

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
