Explanation:
The sum of the interior angles of a triangle will be 180
°
.
Therefore, think of the ratios of 3:4:5 as variables followed by "x" (3x, 4x, and 5x).
Combine like terms and set the equation equal to 180, the amt. of degrees in a triangle:
123
x
= 180
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.

Answer:
3=45
4=60
5=75
Step-by-step explanation:
3x+4x+5x=180. angle sum
12x=180
x=180/12
x=15
