Answer 1

Answer:

The sum of the interior angles of a triangle will be 180°

Therefore, think of the ratios of 5:4:3 as variables followed by "x" (5x, 4x, and 3x).

Combine like terms and set the equation equal to 180, the amt. of degrees in a triangle:

5x+4x+3x= 12x

Now, divide to isolate for

x:(180/12)= 15

, so x = 15

Now, substitute x for 15 in your variables:

3 x , 4 x , and 5 x

3(15), 4(15), and 5(15)

45, 60, and 75 = 180

Therefore, 45 is the smallest angle.
