how many triangles can you make with two side lengths of 6 inches that meet at a 50 degree angle.

Answers

Answer: Exactly One Triangle

======================================================

Explanation:

Recall that by the SAS (side angle side) congruence theorem, if we know that two pairs of sides are the same length and the angles between them are also congruent, then we can conclude the triangles are congruent. This further means that we can only construct exactly one triangle with two side lengths of 6 inches, and they form a 50 degree angle between them. Applying transformations such as rotations, translations, or reflections will not change the triangle.

Side note: This triangle is isosceles because two sides are the same length. It is not equilateral because we would need to have all three angles to be 60 degrees.

Answer:

One triangle only

The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x?

Answers

Answer:

x = 7

Step-by-step explanation:

The 2 angles are adjacent and sum to 180° , that is

11x + 8 + 12x + 11 = 180

23x + 19 = 180 ( subtract 19 from both sides )

23x = 161 ( divide both sides by 23 )

x = 7

so the graph shows a division problem. the green parts represent 1/4 of the rectangle. and that 1/4 has been cut into 5 parts. so i think it would be d.

Simplify the following expression:

2a - 3b - 4a + 2b

a
- 2a - b
b
a + b
c
2a + 4b
d
- a - 4b

Answers

the answer is a. because you need to remember the negatives
the answer is a and the step by step is

2a-4a = -2a so it has to have that
and
-3b + 2b = -b so your answer is clear hope this helps in the future

if a ≤ =6 is a ≤ =12

Answers

Answer:

true

Step-by-step explanation:

since a is smaller than or equal to 6 then it should be smaller than or equal to a bigger value like 12

True cause 6 is greater than a so 12 is obviously greater

The net of a square pyramid is shown below. What are the possible areas for a single face in this net? Check all that apply.

A net with a square base with sides lengths of 5 meters, and 4 triangles with heights of 6 meters.
11 square meters
15 square meters
24 square meters
25 square meters
30 square meters

Answers

Answer: 1,2,and 4. I did it online and got it right!

Answer:

B. 15 square meters (for the triangles)

D. 25 square meters (for the square base)

Bonus: The total surface area would be 85 square meters.

Step-by-step explanation:

The square base is easier to deduce here; simply square 5 to get 25 square meters for the base.

The triangles require some math, however. But it is relatively simple

(5 * 6)/2

30/2

15 square meters for the triangles.

For bonus, I'll find the total surface area.

5² + 4((5 * 6)/2)

First, square 5 to get 25.

25 + 4((5 * 6)/2)

Now multiply 5 * 6 to get 30.

25 + 4(30/2)

Then divide 30 by 2 to get 15.

25 + 4(15)

Now multiply 4 by 15 to get 60.

25 + 60

Lastly, add 25 and 60 to get 85.

The entire square pyramid's surface area is 85 square meters.

I hope this helps! ヽ(*⌒▽⌒*)ﾉ
