Acute, Meaning less than 90 degrees.
Angle: x
complement: 90-x
3x=90-x-14
4x=76
x = 19
90-x= 71
First lets solve for x we know 3x=90. In this case x=30. Now we can solve for y. We know the triangle needs to equal 180 so y+2(30)=180. So we get y=120. Hope it helps
1,260 miles all you have to do is 420x3 because Annie drove 3 times faster.
Step-by-step explanation:
9x - 2 = 4x + 8 → (9-4)x = 8 + 2 → 5x = 10 → x = 10/2 = 5
