Find tan^-1 1.4826 to the nearest degree

A= 131 degrees 3 min or

A = 311 deg 3 min

Step-by-step explanation:

Given is a value -1.14826

We have to find the angle such that

tan A= -1.14826

We know that tangent is negative in II and IV quadrant.

Hence angle A should lie in II or IV quadrant.

First find B such that

tan B =1.14826(removing negative sign)

Hence

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.
