a little bit of help on my hw haha, will mark brainiest

Answer:

x = 93

Step-by-step explanation:

The measure of a straight line is 180°. So,

x + 87 = 180

Subtract 87 from both sides.

x = 93

I hope this helps! Feel free to ask any questions!

Answer:

Step-by-step explanation:

87° + x° = 180°

x° = 180° - 87°

x° = 93°

Answer:

15. $263

Step-by-step explanation:

Answer:

To determine what is the difference between "6 + A" and "6 x A", the logic of the proposed mathematical operations must be explained:

In "6 + A", the value A is added to the initial value 6. Thus, for example, if A were worth 10, to the initial value 6 10 units are added, with which the final value is 16.

In contrast, in "6 x A", the initial value 6 is multiplied by as many times as the value A indicates. Therefore, continuing with the value of A as 10, in this case 6 would be multiplied by 10 times, giving a final value of 60.

Answer:

17.5

Step-by-step explanation:

17 1/2 - 1/2 = 17. We do this to isolate 1/2

1/2 = 0.5

17 + 0.5 = 17.5

1.) Reduction

As you can see Triangle A was reduced in size as a result of Triangle B

2.) Enlargement

Square A is much smaller than square B, making this an enlargement

3.) Enlargement

The quadrilateral shown here gets larger with quadrilateral B

4.) Reduction

This object gets vividly smaller as shown on the graph, making it a reduction  

Answer:

You flipped the triangle over the y axis instead of the x axis

Step-by-step explanation:

instead of changing the flipping the sign of the x coordinate ((-5,5) to (5,5)), you would want to flip the y value, ((-5, 5) to (-5, -5)).

Answer:

x= 23

Step-by-step explanation:

[tex]8x - 77 = 3x + 38 \\ 8x = 3x + 115 \\ 5x = 115 \\ x = 23[/tex]

Answer: a = 122*

The three angles added together form a circle or 360*.

Set a + b + c = 360 and solve for a

a + 66 + 172 = 360

Subtract 238 from both sides to get a

a = 122*

Answer:

D

Step-by-step explanation:

30 + 120 + 30 = 180

that's all

Answer: D

Step-by-step explanation:

D because if you add all the angle measurements it will be equal to 180° ....unlike all the other options which add up to a number other than 180°.

Answer:

The range is the same for both sets of data

Step-by-step explanation:

The two box and whisker plots share neither a median, upper quartile, or a lower quartile, but they do both have a range of 40-55.

Answer: 34

Step-by-step explanation:

Answer:

(7/8 - 4/5)^2 = 9/

1600

= 0.005625

Step-by-step explanation:

Subtract: 7/

8

- 4/

5

= 7 · 5/

8 · 5

- 4 · 8/

5 · 8

= 35/

40

- 32/

40

= 35 - 32/

40

= 3/

40

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - seven eighths minus four fifths = three fortieths

Answer:

1) This HAS a right angle

2) This is an obtuse triangle

Step-by-step explanation:

1)

4² + 3² = 5²

16 + 9 = 25

25 = 25 ✅

2)

5² + 6² = 8²

25 + 36 = 64

61 ≠ 64 ❌

Since c is bigger, this is an obtuse triangle

(Brainliest?)

Answer:

Step-by-step explanation:

(x - 2) => x = 2

f(x) = f(2)

= 2x³ - 5x² + 3x + 7

= 2(2)³ - 5(2)² + 3(2) + 7

= 2×8 - 5×4 + 6 + 7

= 16 - 20 + 6 + 7

= 29 - 20

= 9

Answer:

9

Step-by-step explanation:

Assuming that 6.8 means the area of the triangle, the height would be 1.94.

If this is incorrect, please, don't refrain to tell me. Thank you.

Answer:

x=10

Step-by-step explanation:

Pythagorean Thereom: a^2+b^2 = c^2 when the triangle is right which it is since the 90 degree angle is marked.

a=8 and b=6

8^2+6^2= 64+36 = 100

Take the square root of 100 and get 10.

Answer:

A Scalene

B Isosceles

C Equilateral

Explanation: Interior angles are all different To see why this is so, imagine two angles are the same. The triangle would then be an Isosceles triangle, which has two sides the same length. Similarly, if all three angles are the same, it would be an equilateral triangle and all three sides would be the same length.

Answer:

equilateral acute

Step-by-step explanation:

hello There!

This is an equilateral triangle because all of the angles and sides are congruent

This is also an acute triangle because all of the angles measures are less than 90 degrees
