The ratio of the measures of three angles is 3:8:9. find the measure of each angle of the triangle.
MAXImum [283]

To solve this problem you must apply the proccedure shown below:

1. You have that the ratio of the measures of the three angles is 3:8:9

2. The sum of the interior angle of a triangle is 180degrees

3. Let's say that the measure of each angle is x multiplied by the ratio. Therefore, you can write the following equation and solve for x:

3x+8x+9x=180\\ x=9

4. Therefore, the measure of each angle is:

3(9)=27degrees\\ 8(9)=72degrees\\ 9(9)=81degrees

The answer is: 27degrees, 72degrees,81degrees

I can’t figure out what the half circle means the answer options are 163,129,149 and 186
vodka [1.7K]

Answer: 129

Step-by-step explanation: First find the area of the circle. Since we know the area of a circle is πr²  (pi multiplied by the radius squared) we can find the area of the half circle. The radius is 5 (because radius is half of the diameter)

Area=3.14(5)²

       =3.14(25)

       =78.5

But since this is just a half circle, divide this by 2

That will get 39.25

Then add this to the area of the rectangle (L*W) which is 90

That will get about 129
