Which word describes a triangle with three angles, if each angle measures less than

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
