Answer:
x=6.4
Step-by-step explanation:
5(x-4)=12
5x-20=12
add 20 from both sides
5x=32
divide 5 on both sides
x=6.4
Let
3x----> angle exterior 1
4x----> angle exterior 2
5x----> angle exterior 3
we know that
The exterior angles of any polygon add up to 360 degrees
so
3x+4x+5x=360-------> 12x=360----------> x=30°
The largest of exterior angles is equal to the smallest of interior angles
so
the largest of exterior angles is 5x------> 5*30=150°
the smallest of interior angles is 180°-150°=30°
therefore
the answer is
the smallest of interior angle measure 30 degrees
4x - 5y = 40
4x = 40 + 5y
x = 10 + 5/4y
The x intercept is 10.
