Whats the measure of angle E ?

Mathematics
1 answer:
Sindrei [870]3 years ago

Answer:

57degrees

Step-by-step explanation:

The triangle is an isosceles triangle, hence m<D = m<E (base angles are equal)

Taking the sum of the angles and equating to 180

5x-4 + 4x+1 + 4x+1 = 180

5x+4x+4x-4+1+1 = 180

13x - 2 = 180

13x = 180 + 2

13x = 182

x =182/13

x = 14

Get m<E

m<E = 4x+ 1

m<E = 4(14)+ 1

m<E = 56+1

m<E = 57degrees

Hence the measure of m<E is 57degrees

What is the answer in that Equation
yulyashka [42]
T=2\pi\sqrt{\dfrac{m}{k}}\ \ \ \ \ |divide\ both\ sides\ by\ 2\pi\\\\\sqrt{\dfrac{m}{k}}=\dfrac{T}{2\pi}\ \ \ \ \ \ |square\ both\ sides\\\\\dfrac{m}{k}=\dfrac{T^2}{4\pi^2}\ \ \ \ \ \ |multiply\ both\ sides\ by\ k\neq0\\\\\boxed{m=\dfrac{T^2k}{4\pi^2}}

One day, a person went to a horse racing area. Instead of counting the number of humans an horses, he conuted 74 heads and 196 l
Komok [63]
A human has 1 head and 2 legs.
A horse has 1 head and 4 legs.

Let's make two equations from what we know.

There were a total of 74 heads.
There were a total of 196 legs.

Let's call humans 'x' and horses 'y'

The total number of heads were 74.
Humans have 1 head, and so do horses.

Our first equation is:
x + y = 74

There were a total of 196 legs. 
Humans have 2 legs, and horses have 4 legs.

Our second equation is:
2x + 4y = 196

Our two equations are:

x + y = 74
2x + 4y = 196

We need to solve this system of equations to find out how many humans and horses were at this racing event.

Multiply the first equation by 2.

2(x + y) = 2(74)
2x + 2y = 148

Our two equations are:

2x + 2y = 148
2x + 4y = 196

Subtract the first equation from the second equation.

2x - 2x + 2y - 4y = 148 - 196
2y - 4y = 148 - 196
-2y = - 48

Divide both sides by -2

y = 24

That means that there were 24 horses.

We can plug back in y = 24 into our first equation to find out how many humans there were.

x + y = 74
x + 24 = 74
x + 24 - 24 = 74 - 24
x = 50

There were 50 humans.

At the horse racing event, there were 24 horses and 50 humans.

Your final answer is B. 24 horses and 50 humans.

Answer:

It would be all of the above.

Step-by-step explanation:

An example of a polynomial is:

2x^3 - 4x^2 +1x -8

Note how there are exponents, such as ^3 for example. There is also a variable, in this case x. Lastly, there are constants, which are numbers by themselves.
