What is the length of the diagonal of a poster board with dimensions 22 inches by 28 inches

35.6 inches

Step-by-step explanation:

using Pythagoras principle we get

Length of diagonal=√(28^2+22^2)

Length of diagonal=√(28x28+22x22)

Length of diagonal=√(784+484)

Length of diagonal=√(1268)

Length of diagonal=35.6

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.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
