Answer:
84 degrees.
Step-by-step explanation:
First, let's define what a complementary angle is. It's when two angles add up to 90 degrees. So we do 90-6=84 and 84+6 does in fact equal 90, so they are complementary.
Answer:
The answer is (-4/3)
Step-by-step explanation:
3(x − 4) = 12x
Multiply (x – 4) by 3 we get,
3(x – 4) = 12x
3x – 12 = 12x
3x – 12x – 12 + 12 = 12x – 12x + 12
-9x = 12
-9x/(-9) = -12/9
x = -4/3
Thus, The value of x is -4/3

Answer:
Acute angle, right angle, obtuse angle and reflex angle.
Step-by-step explanation:
Acute angle -
0° < θ < 90°
Right angle -
θ = 90°
Obtuse angle -
90° < θ < 180°
Reflex angle -
θ > 180°
Formula for circumference of circle:
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
Answer: Circumference of the circle is 25.1 cm (Rounded to 1 decimal place)
