Answer:

The area of shaded sector

Formula A = (θ / 360°) × πr²

θ=360°-140°=220°

r=18yd

We have A=(220/360)×3.14×(18)²

=621.72yd²

Area of sector is621.72yd².

valentina_108 [34]

Answer:

the length of the altitude is 7.5 cm

Step-by-step explanation:

In a Δ ABC, $\overline {BC}$ is the altitude

If an altitude is drawn to the hypotenuse of the right angle triangle as shown in the image attached below; Then:

$(AD)^2 = AD*AC \\ \\ x^2 = 5*11.25 \\ \\ x^2 = 81.25 \\ \\ x = \sqrt{81.25} \\ \\ x= 9.01$

NOW;

$(BC)^2 = DC*AC \\ \\ z^2 = 11.25 *16.25 \\ \\z^2 = 182.8125 \\ \\ z= \sqrt{182.8125} \\ \\ z= 13.52$

Finally; the altitude which is $\overline {BD}$ is calculated as:

$(BD)^2 = AD*DC \\ \\ y^2 = 5*11.25 \\ \\ y^2 = 56.25 \\ \\ y = \sqrt{56.25} \\ \\ y= 7.5$

Thus; the length of the altitude is 7.5 cm

Write sin81 in terms of cosine

strojnjashka [21]

Answer:

Since 81° is less than 90, we can express this in terms of a cofunction. sin(θ) = cos(90 - θ) sin(81) = cos(90 - 81) sin(81) = cos(9)

Morgarella [4.7K]

Answer:

= 4 1/6 ---------------> final answer

Step-by-step explanation:

1 2/3 cup of sugar

That is : 5/3 cups of sugar for 1 cookie recipe

So for 1 recipe ------------- 5/3 cups of sugar

hence for 2 1/2 recipe ---------------> (5/3) * (5/2)

= 25/6

= 4 1/6 ---------------> final answer
