Given that the measure of ∠ADC = (7x + 2)° and arc AC = (8x - 8)°

We need to determine the measure of ∠ABC

<u>The value of x:</u>

The measure of ∠ADC can be determined using the formula,

m\angle ADC=m \widehat{AC}

Substituting the values, we get;

7x+2=8x-8

-x+2=-8

     -x=-10

       x=10

Thus, the value of x is 10.

<u>The measure of ∠ADC:</u>

Substituting the value x = 10 in the measure of ∠ADC = (7x + 2)°

We have;

\angle ADC=(7(10)+2)^{\circ}

\angle ADC=(70+2)^{\circ}

\angle ADC=72^{\circ}

Thus, the measure of ∠ADC is 72°

<u>The measure of ∠ABC:</u>

The measure of ∠ABC can be determined using the central angle theorem.

Thus, we have;

\angle ADC=2\angle ABC

     72^{\circ}=2\angle ABC

     36^{\circ}=\angle ABC

Thus, the measure of ∠ABC is 36°

Hence, Option A is the correct answer.

denis-greek [22]

Answer:

254 4/7 or 254.34 ft² (it depends on which method you use.)

Step-by-step explanation:

To find the area of a circle, the formula is πr².

I'll use both 22/7 and 3.14 as pi, so I'll end up with two different answers. Just choose the more reliable one.

22/7 version:

22/7 * 9^2

22/7 * 81/1

1782/7

254 4/7 ft²

3.14 version:

3.14 * 9^2

3.14 * 81

314 - (3.14 * 19)

314 - 62.8 + 3.14

251.2 + 3.14

254.34 ft²

As I said, I ended up with two different answers. You also had said not to round my answer, so the 22/7 version has a mixed number.

Please help! you have to find the surface area of the inage below!
viva [34]
Your answer would be 64 in².

To find the surface area, you just need to find the area of each of the shapes shown and add them together.
We can find the area of one of the triangles by doing:
(base × height)/2
(6 × 4)/2 = 24/2 = 12

As there are 4 identical triangles, the area of all of them would be 12 × 4 = 48 in².

Now we need to find the area of the square in the middle, which would be 4 × 4 = 16 in².

Adding these together gives us 16 + 48 = 64 in²

I hope this helps!

There are 96 female staff in an office. If the ratio of male staff to female staff is 3:4, find the number of male staff​.
Alex

Answer:60 male staff

Step-by-step explanation:

Ok, there are 96 female staff. The ratio of male to female is 3:4. We’re going to use a proportion which looks like this. 3/4 = x/96. X is a variable that takes the place of the male staff since we don’t know what it is. Now, the question is what do we do to get from 4 to 96. So 96/4 = 24, so 4 x 20 = 96. To keep this ratio equivalent whatever you do to the top you have to do to the bottom so 4 x 20 = 96 and 3 x 20 = 60. So there are 60 male staff.
