How to know when to use c2=a2+b2 or a2+b2=c2 in a question that doesnt have a shape

Mathematics

Viefleur [7K]2 years ago

Step-by-step explanation:

A flagpole is 53 feet tall. Most of the time, this will be a vertical side of the triangle.

The flagpole and the ground are perpendicular to each other so they should form the legs of the triangles, this the triangle will be a right angle.

The rope will be the hypotenuse, the side opposite of the right angle.

Two lines are intersecting. What is the value of x? Enter your answer in the box. (x + 23) (2x + 4)° Help! Please!!!
Delicious77 [7]

Answer:

x = 51^o

Step-by-step explanation:

Given

Intersecting lines

Required

Find x

To do this, we make use of:

x + 23^o + 2x + 4^o = 180^o --- angle on a straight line

Collect like terms

x  + 2x = 180^o - 4^o - 23^o

3x = 153^o

Divide both sides by 3

x = 51^o

Write a recursive formula for each sequence given or described below.
valentinak56 [21]

Answer:

a_{n} =a_{n-1} +3000 and a₁ =30000 for n = 2,3,4,5,6, ......

Step-by-step explanation:

Doug has joined a job with a starting salary of $30000 per year.  

Hence, if a₁ is the salary of Doug in the first year, then  

a₁ =30000

Now, each year Doug will receive a raise of $3000 in his salary.

Hence, in the 2nd year, his salary(a₂) will become ( a₁ +3000) per year.

Again, in the 3rd year, his salary(a₃) will become ( a₂ +3000) per year.

Therefor, in the similar manner the recursive formula for his salary in each year will be given as a_{n} =a_{n-1} +3000 and a₁ =30000 for n = 2,3,4,5,6, ...... {aₙ is the yearly salary of Doug in the nth year} (Answer)

Consider the following triangle side lengths and determine if the triangle could exist. Justify your answer. Part A: 21,18,17 Pa
Misha Larkins [42]

Answer:

A yes, B no

Step-by-step explanation:

The triangle inequality states that the sum of any 2 sides of the triangle must be greater than the third side.

A Given 21, 18, 17 , then

21 + 18 = 39 > 17

21 + 17 = 38 > 18

18 + 17 = 35 > 21

Thus the triangle could exist

B Given 3, 12, 8 , then

3 + 12 = 9 > 8

3 + 8 = 11 < 12 ← fails the test

Thus the triangle does not exist

Complete the equation so that it is
Setler [38]

Answer:

Any number other than 2

Step-by-step explanation:

Well if we plug in any number other than 2 like 1  for the blank and distribute,

the right side becomes,

3x + 6 = 3x + a number other than 6

Parallel lines have the same slope but different y intercept.

Look at the image below ↓

<em>Thus,</em>

<em>to make the equation have no solution the blank has to be any number other than 2.</em>

<em />

<em>Hope this helps :)</em>

Does anyone know about this?:)
lina2011 [118]

Answer:

1. 148

2. 17

Step-by-step explanation:

1. m<FEC + m<CED = m<FED

  32      +       m<CED    =  180

  m<CED = 180 - 32

  m<CED = 148

2. m<CEA + m<AED = m<CED

(6x - 20) + (3x + 18) = 151

9x - 2 = 151

9x = 153

x = 17
