The ratio of the measure of the three angels in a triangke is 15;8;13 find the measure of the angles

 45,  117,18

Step-by-step explanation:

The ratio of the three angles are

5:13:2

Multiply that by x

5x  13x  2x

The sum of the three angles is equal to 180.

5x+13x+2x = 180

Combine like terms

20x = 180

Divide by 20

20x/20 = 180/20

x = 9

The angles are

5x = 5*9 = 45

13x = 13*9 = 117

2x=2*9 = 18

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
