Which angle is complementary to DFE? Pls answer
Answer:
<DFA
Step-by-step explanation:
When combined (<DFA and <DFE), they'll form 90 degrees which will make them complementary
Answer:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle. When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
The complement of −135° is the angle that when added to −135° forms a right angle (90° ).

Caden, Zoe, and Sophia shared a pizza. Caden ate 20 percent of the pizza. Zoe ate 50 percent more of the pizza than Caden ate. Noah ate 50 percent more of the pizza than Zoe ate, and Sophia ate the rest of the pizza. Find the percentage of the pizza that Sophia ate.
Answer:
Step-by-step explanation:
c=.2, z=1.5(.2), n=1.5(1.5).2
s+c+z+n=1
s+.2+1.5(.2)+1.5(1.5).2=1
s+.2+.3+.45=1
s+.95=1
s=.05
So Sophia ate 5% of the pizza
Answer:
Sophia ate 5%.
Step-by-step explanation:
Caden ate 20%. Zoe ate 50% more than him, so 150% of 20%. That is 20+half of 20, which is 30. So zoe ate 30%. Noah ate 50% more than her, so 150% of 30%, which is 45%. Add them together and get 95%. That leaves 5% for Sophia to eat.

Cuántas diagonales tendría una figura de 8 lados?

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 12 cm, and the base has a
radius of 3.5 cm. How much water is needed to fill 50 cups?
Use 3.14 for pi and do not round your answer.
Answer: 7693cm
Step-by-step explanation:
The volume of a cone is given as:
= 1/3πr²h
where π = 3.14
radius = 3.5cm
height = 12
Volume = 1/3πr²h
= 1/3 × 3.14 × 3.5² × 12
= 153.86cm³
Therefore, the amount of water that is needed to fill 50 cups will be:
= 153.86 × 50
= 7693cm

Please help me with finding the length of AC. I’ll make this 20 points since it’s kinda long. Please don’t guess my grades depends on it
Since the triangle is a right angled, to find one side we should use the pythagoras theorem.
The longed side of the triangle is called the hypotenuse.
In equation form: x² + y² = z²
Therefore: 12² + x² = 13²
114+x²= 169
x²= 169-114
x²= 55
x = 7.41
Therefore the length of AC = 7.41

What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
Given that Ms Aluma is 165 cm tall and She wants to find her height in meters. Therefore, if we divide her height in centimeters by 100 to find her height in meters.
Since 1 meter is equal to 100 cm, therefore, the method used by Ms. Aluma is correct. Therefore, the height of Unit conversion is,
Height of Ms. Aluma = 165 cm
= 165/100 meters
