Step-by-step explanation:

1. No: angles add to more than 180 deg.

2. Yes: each side's length is between the sum and difference of the lengths of the other two sides.

3. No: not every side's length is between the sum and difference of the lengths of the other two sides.

4. Yes: for example, place the 50 deg angle between the two given sides. Another side will then make the triangle.

5. Yes: for example, use 3 cm as the short leg in a 30-60-90 right triangle.

Which equation can be used to represent “ three minus the difference of s number and one equals one-half of the difference of th

puteri [66]

Answer:

1 - s = s - 4 (s=2.5)

Step-by-step explanation:

If you write the equation down, you get 3-(s-1) = 3(s-4), which (when you divide each side by 3), gives you -s+1=s-4. If you add s to both sides, you get 1 = 2s - 4, and after adding 4, you get 2s = 5, and s = 2.5

If the triangles in the figure are similar what is the length of side b?

kolezko [41]

Answer:

A 36

Step-by-step explanation:

We can determine the scale factor

From triangle ABC BC =9

DEF EF = 90

We multiply by 10

The scale factor is 10

AC ( 10) = DF

We know DF = 360

b * 10 = 360

Divide each side by 10

10b/10 = 360/10

b = 36

Worth 20 points and a brainliest!

krek1111 [17]

Bim's grade in English is a "A" or 95%. He has one assignment left and can not do it. The assignment is worth 20 points. If Bim fails the assignment and gets 0 points. What will his grade be after failing the assignment?
We will add Bim's grades : 95% + 0%

Then we will divide by 2!
Therefore his grade will drop to a 97.5!
Hope I helped!

In the given diagram, the length of diagonal IE is 30. The correct option is (2) 30

<h3>Calculating the length of a diagonal of a Rhombus </h3>

From the question, we are to determine the length of diagonal IE

From the given information,

/TG/ = 16

∴ /RG/ = 16÷2 = 8

NOTE: The diagonals of a rhombus bisect each other at right angles

Then,

/GE/² = /ER/² + /RG/² (<em>Pythagoras' theorem</em>)

From the given information, the perimeter of the rhombus is 68

Since all the sides of a rhombus are equal to one another,

Then,

/GE/ = 68÷4

/GE/ = 17

Thus,

17² = /ER/² + 8²

289 = /ER/² + 64

/ER/² = 289 - 64

/ER/² = 225

/ER/ = √225

/ER/ = 15

But,

/IE/ = 2 × /ER/

∴ /IE/ = 30

Hence, the length of diagonal IE is 30. The correct option is (2) 30
