acute triangle
Step-by-step explanation:
A triangle with all angles less than 90 degrees has all angles that are acute.
Acute angles are less than 90 degrees
x = 6
Explanation:
y = x - 4
26 = 4x + y
If y = y, then we can rewrite this system as this: 4x + x - 4 = 26
Then we combine like terms and add 4 on both sides to give us 5 x = 30 . Divide by 5 on both sides and we arrive at the solution: x = 6
