Mathematics
1 answer:
Allisa [31]3 years ago
8 0

Answer:

A) 3a = 180°

B) a+ 55° + 36° = 180°

C) x + y + z = 180°

Step-by-step explanation:

The answer is the A option since all the side of the triangle could be the same, making it an equilateral triangle. ( 60° + 60° + 60° = 180° )

The sum means that all the angles are added, not necessarily being similar terms, which equals to 180°.

The terms don't have to be similar, for instance the B option,

a+ 55° + 36° = 180°

since you could find the value of a.

The same thing goes for C.

(Extra)

It is not D since x is multiplied with 3, not giving the sum.

It is not E since all the 3 terms are multiplied, not giving the sum.

are the rational numbers a subset of all real numbers? are the rational numbers a subset of the irrational numbers? explain
Nastasia [14]

Answer:

see below

Step-by-step explanation:

<u>are the rational numbers a subset of all real numbers?</u>

yes of course

by definition the real numbers is the union of the rational numbers and the irrational numbers

so we can say that the rational numbers are a subset

and every rational number is part of the real number

<u>are the rational numbers a subset of the irrational numbers?</u>

No

the rationals numbers are all those numbers that you can write as p/q with q different of 0, and the irrationals numbers are those that you cannot write as a fraction

so as you can see those are two completely different types of number, to be a subset every rational number must be in the irrationals , and by the definition we know it can't happen

A 6-foot man walks on level ground toward a 60 foot flag pole. He notes different angles of elevation θ to the top of the pole w
krek1111 [17]

Answer:

  a)  x = 54/tan(theta)

  b)  theta = arctan(54/x)

Step-by-step explanation:

a) The tangent ratio is the ratio of the side opposite an acute angle in a right triangle to the adjacent side. For the angle of elevation, the adjacent side is the distance x to the flagpole. The side opposite is the 54-foot difference between the top of the man's head and the top of the flagpole. So, we have ...

  tan(theta) = 54/x

Solving for x gives ...

  x = 54/tan(theta)

__

b) Solving the first equation in the previous part for theta involves the inverse tangent function:

  theta = arctan(54/x)

Answer:

1. 3(x^2+10x-24)

Step-by-step explanation:

3x^2 +30x-72

so you want to see what each element has in common with the whole equation.  In this case, everything is divisible by 3 so we take out the 3.

3(x^2+10x-24)
