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: $27degrees, 72degrees,81degrees$

kotegsom [21]

Answer:

Jack ran 38 km and Ted ran 43 km.

Step-by-step explanation:

Let Jack’s displacement be $x$

$x + (x+5) = 81$

$2x + 5 = 81\\2x = 76$

$x = 38 km$

$x+5 = 38 + 5\\x+5 = 43km\\$
