Answer:
obtuse triangle
Step-by-step explanation:
it is obtuse because it needs to have all 3 sides to be acute to be an acute angle and it doesn't have any 90° angles so it has to be obtuse. Also because to be an obtuse it has to have 2 acute angles and 1 obtuse angle. Hope this helps!!
It's takes about 4.6 hours if your rounding it to the nearest tenth
It would be -6.
This makes use of the Remainder Theorem.
Complement angles mean that the sum of them = 90°
Say one if them = X
then the 2nd will be 5X
X+5X =90°
6X = 90°
X = 90/6
X = 15°
Therefore,
the 1st angle X = 15°
the 2nd angle 5X = 15 ×5 = 75°
Answer:
x=6
Step-by-step explanation:
Simplifying
3(2x + -8) = 12
Reorder the terms:
3(-8 + 2x) = 12
(-8 * 3 + 2x * 3) = 12
(-24 + 6x) = 12
Solving
-24 + 6x = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '24' to each side of the equation.
-24 + 24 + 6x = 12 + 24
Combine like terms: -24 + 24 = 0
0 + 6x = 12 + 24
6x = 12 + 24
Combine like terms: 12 + 24 = 36
6x = 36
Divide each side by '6'.
x = 6
Simplifying
x = 6
