1. What is the measure of angle B04?
2. What is the measure of angie BDA?
3. What is the measure of angle BCA?

Answers

Using the inscribed angle theorems, the measure of the indicated angles are:

1. m∠BOA = 30°

2. m∠BDA = 15°

3. m∠BCA = 15°

What is the Inscribed Angle Theorems?

Based on the inscribed angle theorems, the following relationships are established:

Inscribed angle = 2(measure of intersected arc)Central angle = measure of intersected arc

Given:

Intercepted arc BA = 30°

1. ∠BOA is central angle

Thus:

m∠BOA = 30° (inscribed angle theorems)

2. ∠BDA is inscribed angle.

m∠BDA = 1/2(30) = 15° (inscribed angle theorems)

3. m∠BCA = m∠BDA  = 15° (inscribed angle theorems)

Answer:

She made $1230 more on printed shirts than plain shirts in 25 weeks.

Step-by-step explanation:

Hi,

Okay, I have to admit, this is pretty complicated. But, it's not impossible :) First things first, we know that the equation in the table is the number of shirts sold after W number of weeks. We know that we need to, first, find the total number of shirts sold in 25 weeks.

The equation for the plain shirts is 5w -4. Let's start with that.

Plugin 25 for w to find the total number of plain shirts sold after 25 weeks.

5w - 4

5(25) - 4

= 121

She sold 121 plain shirts after 25 weeks. But we're not done yet, we still have to see how much money she made after selling 121 plain shirts. To do this, we have to multiply the total number of plains shirts sold by 15. (we know that each plain short costs $15, that's why we're multiplying it by 121)

When you do this...

121 x 15

You get...

$1815

She got $1815 after 25 weeks just for selling plain shirts.

Now, let's find the total cost of printed shirts after 25 weeks.

The equation for the printed shirts if 8w + 3.

8w + 3

8(25) + 3

= 203

She sold 203 printed shirts in 25 weeks. Let's find the cost. Each printed shirt costs $15 so we need to multiply 203 by 15.

203 x 15

You get...

$3045

She made $3045 by selling printed shirts in 25 weeks.

Now, we have to subtract $3045 by $1815 to find how much more she made. You get...

3045 - 1815

= $1230

She made $1230 more on printed shirts than plain shirts in 25 weeks.

I really hope this helps :)

Find the area of triangle ABC (I’ll give you the branliest answer if correct) :)

To find the are of a triangle, you multiply the dimensions as you would a rectangle, but divide the product by 2.

Example:

The dimensions of triangle B are 4 and 9.

4x9=36

Now divide.

36/2=18

So the area of triangle B is 18.
