The dimensions of a rectangle are 3.61 cm and 2.57 cm, each correct to 3 significant figures.

a) Write down the upper and lower bounds for each dimension

b) Find the upper and lower bounds of the area of the rectangle.

c) Write down the upper and lower bounds of the area correct to 3 significant figures

a) 3.605 and 3.615, 2.565 and 2.575

Step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

answer: 414,377,008

step-by-step explanation:

just multiply it
