Given:

Mathematics
1 answer:
Lubov Fominskaja [6]3 years ago
5 0

Answer:

Step-by-step explanation:

I'm not very familiar with 2 column proofs but the following is how we'd prove it in the UK:

AB ≅ AC  ( Given)

BE ≅ CE   (Given)

Line segment AE is common to Δ's ABE and ACE

so the 2 triangles are congruent.   (By SSS).

< BAD  ≅ < CAD ( as triangles ABE and ACE are congruent).

AD is common  to Δ's BAD and CAD.

AB  ≅ AC (given)

So Δ's BAD and CAD are congruent by SAS.

Therefore < ADB  ≅ < ADC ( as triangles BAD and CAD are congruent).

m < BDE = 180 - m < ADB  and

m < CDE = 180 - m < ADC  (both  angles are adjacent)

So since < ADB  ≅ < ADC,

< BDE    ≅ < CDE.

A certain pizza parlor has 7<br> different toppings. How many two-<br> topping pizzas are possible?
Nezavi [6.7K]

Answer:

21

Step-by-step explanation:

Ok, so this may be confusing but I’ll explain.

Here is a very simplified diagram:

1-2, 1-3, 1-4, 1-5, 1-6, 1-7

2-3, 2-4, 2-5, 2-6, 2-7

3-4, 3-5, 3-6, 3-7

4-5, 4-6, 4-7

5-6, 5-7

6-7

*Note- I did this in about 30 seconds and on my phone so it is very simplified *

Each number, 1-7, is supposed to represent a different ingredient and they are put together to represent the two-ingredient combinations.

For example: 1-2 could represent pepperoni and sausage, and 1-5 could represent pepperoni and olives. This would mean that the 1 represents pepperoni, 2 represents sausage, and 5 represents olives.

If you count the number of combinations in each row, there are 21 combinations. This is because I made sure there are no repeats (2-3 AND 3-2) and because there wouldn’t be any doubles (1-1 or 2-2)

inessss [21]

Answer:

36 ounces.

Step-by-step explanation:

The ratio being 24:8 can be simplified to 3:1

Multiply the one (the vinegar) by a factor of 12

What happens to one side has to happen to the other

12(3:1)

36 ounces.

A 26-foot long ladder is leaning against a building at a 60° angle with the ground.
agasfer [191]
Sine = opposite / hypotenuse
Sin60 = h / 26       
Multiply both sides by 26
Sin60 (26) = h
h = (Sin60)26
