Acute. Step-by-step explanation: Using the Triangle Inequality Theorem you know that the sum of the lengths of two sides of a triangle are greater than the length of the third side.
Answer:
x = - 1
Step-by-step explanation:
3(x + 1) = - 2(x - 1) - 4 ← distribute parenthesis on both sides
3x + 3 = - 2x + 2 - 4
3x + 3 = - 2x - 2 ( add 2x to both sides )
5x + 3 = - 2 ( subtract 3 from both sides )
5x = - 5 ( divide both sides by 5 )
x = - 1
Salutations!
<span>Are obtuse angles always, sometimes, or never equal to 180°?
Obtuse angles are angles </span>whose measure is greater than 90° and less than 180°. Its not always the case that an obtuse angle should be exact 180 °. So I reckon t would be sometimes, as its not always 180 °.
Hope I helped.
