The diagram shows a sector of a circle, radius 45 cm, with angle 84º. 45 cm
840
Diagram NOT
accurately drawn
Calculate the area of the sector.
Give your answer correct to 3 significant figures.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

using pemdas, (order of operations) you'll see the answer is 24.

=

x=0.8898305 is the answer to that equation

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
