Answers

Answer:

Sum = 180 degrees

Angle A = 85 degrees

Angle B = 95 degrees

Step-by-step explanation:

A triangle's angles will always be equivalent to 180 degrees when finding their sum.

For this triangle, 80, 15, and A will equal 180 degrees.

80 + 15 + A = 180

Combine like terms

95 + A = 180

Isolate variable A by subtracting both sides by 95

A = 85

85 degrees

Similar to a triangle, a straight line is also equivalent to 180 degrees

A + B = 180

Plug in the value for variable A

85 + B = 180

Isolate variable B by subtracting both sides by 85

B = 95

A number h added to −3 is at most 3.4.

Answers

Answer:

-3 + h ≤ 3.4

Step-by-step explanation:

Let the unknown number be h. If A number h added to −3, this is expressed as;

-3 + h

Since the result is at most 3.4, it means that it cannot be greater than 3.4, hence the best inequality sign to use is a less than or equal to sign ≤. The required expression will be;

-3 + h ≤ 3.4

Which set of sides would NOT make a triangle?

Answers

Answer:

the 3rd one

Step-by-step explanation:

Answer:

A) 12 cm, 7 cm, 5 cm

Step-by-step explanation:

For the side lengths of a triangle to be true, the smaller side lengths can not add up to be smaller or equal to the larger side length. In this case, the smaller lengths are 7 and 5. Add them to get 12, the same side length as the largest side. The smaller sides (7 and 5) add to be equal to the longer side length, so these side lengths are FALSE. The other 3 sides of triangles are TRUE.

ZA and B are supplementary angles.
If ZA measures 45°, then what is the measure of ZB?
O 35
O 45
O 135
O 145

Answers

Answer:

135°

Step-by-step explanation:

a supplementary angle is equal to 180°. since you already have the measure of ZA, all you need to do is subtract 45°, the measure of ZA, from 180°, the total measure of a supplementary angle, in order to figure out the measure of ZB.

180 - 45 = 135, therefore the measure of ZB = 135°.

Answer:

Pythagorean Theorem:

a^2 + b^2 = c^2

6^2 + b^2 = 12^2

36 + b^2 = 144

b^2 = 108

b = 10.4

Let me know if this helps!

Answer

10.4

Step-by-step explanation:

pagathorium theorem, A^2 + B^2 = C^2. You have the C and one length, the other can be found. So 6^2 + B^2 = 12^2. Then you have 36 + B^2 = 144. You use simple algrebra to solve the rest. 144-36 is 108. Now it's B^2 = 108. The opposite of squared is sqare root. So now you can have B all along (Missing side) with the answer ebing B = 10.392 or rounded 10.4

Maria has $3,000 in the bank, has a home worth $150,000, and has a $75,000 home loan. She also has $10,000 in Investments and a $15,000
student loan. What is Maria's net worth? Show your work please

Answers

Answer:

$73,000

Step-by-step explanation:

To answer, you simply subtract and add numbers along the way. First, because Maria has money in the bank and her home is worth money, we add those numbers together:

3,000 + 150,000 = 153,000

Now, because she has a home loan, that means she owes money, so you subtract that from her net worth so far:

153,000 - 75,000 = 78,000

Her investments money would be added:

78,000 + 10,000 = 88,000

And another student loan would be subtracted:

88,000 - 15,000 = 73,000

So, Maria's net worth is $73,000

Hope this helps :)


Identify the variables in this Algebraic Expression
X+ 4y - 9

Answers

Answer:

The expression [tex]x + 4y - 9[/tex] has two variables x and y.

Step-by-step explanation:

What is a variable?

A variable is a letter, for instance [tex]x[/tex] or [tex]y[/tex], that represents an unknown number.

Given the expression

[tex]x + 4y - 9[/tex]

The given expression has three terms which are x, 4y, and -9.

Here:

The term 'x' is the unknown variable x.The term '4y' has a coefficient (the number next to a variable y) of 4.The term '-6' is a constant.

As we already know that a variable is a letter, for instance x or y, that represents an unknown number. In other words, the values of x, or y are unknown to us.

Thus, the expression [tex]x + 4y - 9[/tex] has two variables x and y.
