The diagram consists of a large circle and four small circles. Each of the smaller circles has radius 1 and touches the large circle and the two small circles next on either side of it
To 3 significant figures, find the value of the shaded area in square units!

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

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
