Answer:

180°

Step-by-step explanation:

The sum of the measures of the interior angles formed by the boundary of this team pennant.

The shape of pennant is similar to triangle. It means pennant has 3 sides and 3 angle.

It would be triangle. As we know, the sum of measure of interior angles of a triangle is 180°

∠1 + ∠2 + ∠3 = 180°

Hence, The sum of measure of angles formed by boundary of pennant is 180°

I think the correct answer from the choices listed above is option C. The sum of the measures of the interior angles formed by the boundary of this team pennant should be 180 degrees since all triangles has a sum of interior angles which is 180 degrees. Hope this answers the question.

Answer:

5.16

Step-by-step explanation:

Since after x=3, value of y starts decreasing for increasing values of x, let's choose. Also we need to find f(x) for x=3.4

x=3,4,5 and f(x)=7,3,1 to find lagrange polynomial

P(x)= ((x-x2)(x-x3)y1)/((x1-x2)(x1-x3) + ((x-x1)(x-x3)y2)/((x2-x1)(x2-x3) + ((x-x1)(x-x2)y3)/((x3-x1)(x3-x2)

P(x)= ((x-4)(x-5)7)/((3-4)(3-5)) + ((x-3)(x-5)3)/((4-3)(4-5)) + ((x-3)(x-4)1)/((5-3)(5-4))

P(x)= x² -11x+31

P(3.4)= 5.16
