Answer 1

Answer: To find whether or not the angles form a triangle, all you have to do is add all of the angles together. To be a triangle, they must equal exactly 180°.

If all of its angles are the same, it’s an equilateral triangle.

If none of its angles are the same, it’s a scalene triangle.

If 2 of its angles are the same, but one is different, it’s an isosceles triangle.

If it has an angle of 90°, it’s a right triangle.

If all of its angles are less than 90°, it’s an acute triangle.

If it has an angle greater than 90°, it’s an obtuse triangle.

1. 86+53+41= 180
It’s a triangle.
None of the angles are the same, it’s scalene.
The angles are all less than 90°, it’s acute.

2. 47 + 84 + 56 = 187
Not a triangle.

3. 70 + 22 + 68= 160
Not a triangle.

4. 54 + 97 + 29= 180
It’s a triangle.
None of the angles are the same, it’s scalene.
It has an angle greater than 90°, it’s obtuse.

5. 33+ 90 + 57 = 180
It’s a triangle.
None of the angles are the same, it’s scalene.
It has an angle of 90°, it’s a right triangle.

6. 28 + 64 + 100 = 192
Not a triangle.

7. 11 + 101 + 60= 172
Not a triangle.

8. 94 + 35 + 51 = 180
It’s a triangle.
None of the angles are the same, it’s scalene.
It has an angle greater than 90°, it’s obtuse.

9. 52 + 83 + 45 = 180
It’s a triangle.
None of the angles are the same, it’s scalene.
The angles are all less than 90°, it’s acute.

10. 65 + 78 + 37 = 180
It’s a triangle.
None of the angles are the same, it’s scalene.
The angles are all less than 90°, it’s acute.

Tricia had 4 1/8 yards of fabric to make curtains. When she finished she had 2 3/8 yards of fabric left. She said she used 2 2/8 yards of fabric for the curtains. Do you agree?

Answers

Well for this you have to do 4 1/8 - 2 3/8. You cannot subtract 1 - 3, so you have to take away 1 from three and add 8 to 1 so now the equation is 3 9/8 - 2 3/8. This is equal to 1 6/8 or 1 3/4, so no, she did not use 2 2/8 yards of fabric.

No because if you add up the fabric she 'used' and the fabric she made to make the curtains it doesn't match up with the original yards of fabric she had to make the curtains.

2 3/8+ 2 2/8= 4 5/8

4 5/8 is the supposedly original fabric she had. It's only 1/2 off from the original fabric of yards.

So no I don't agree.

Rani bought 9 similar notebooks she gave the cashier $10 and received change of $5.05 what was the cost of 1 notebook

Answers

The answer is $0.55. For you to get the answer first you must subtract 5.05 from 10.00, which is 4.95. Then you divide that with 9. Finally you get 0.55.

Hope that helps you. :)

she paid 4.95 divide this by 9 = 0.55

What is the value of z?

Answers

Answer:

The value of the z is 12 .

Step-by-step explanation:

Definition of vertically opposite angle .

Vertically opposite angles is defines angles opposite to each other when two lines cross eachother .

Thus

(5z + 8)° = (4z + 20)°

(5z + 8) = (4z + 20)

Open the bracket

5z + 8 = 4z + 20

5z - 4z = 20 -8

z = 12

Therefore the value of the z is 12 .

5z+8=4z+20

5z-4z=20-8

z=12

Which fraction is the reciprocal of 5 2/3?I NEED HELP ASAP! PLEASE PLEASE PLEASE HELP! I NEED HELP NOW!

A. 2/15

B. 3/17

C. 17/3

D. 13/2

Answers

B.

Okay, so the fraction 5 $(2)/(3)$ ... 5, in terms of thirds, is 15/3, plus ⅔ = 17/3.
The reciprocal of that is just upside-down— 3/17.

You would need to make the fraction a improper fraction and reverse it. It's improper fraction would be 17/3, flip that around and you will get 17/3. The answer is B.
