Now,

x + 80° + 55° = 180° (◆ The sum of interior

angle of triangle is

180°)

or, x = 180° - 135°

◆ x = 45°

it's help you...

Thank you♥♥

Answer:

The value of x is \boxed{\sf{{45}^{\circ}}}

Step-by-step explanation:

<h3><u>Solution</u> : </h3>

Here we have given two angles of triangle are 80⁰,55⁰.

We need to find the third angle of triangle (x).

  • As we know that the sum of interior angles of triangle is 180⁰.

Now, According to the question.

{\twoheadrightarrow{\sf{ \:  \: Sum \:  of \:  interior  \: angles = {180}^{0}}}}

{\twoheadrightarrow{\sf{ \:  \: {80}^{0} +  {55}^{0} + x= {180}^{0}}}}

{\twoheadrightarrow{\sf{ \:  \: {135}^{0} + x= {180}^{0}}}}

{\twoheadrightarrow{\sf{ \:  \: x= {180}^{0} - {135}^{0}}}}

{\twoheadrightarrow{\sf{ \:  \: x = {45}^{0}}}}

\star \:  \: {\underline{\boxed{\tt{\red{x =  {45}^{0}}}}}}

Hence, the value of x is 45⁰.

\begin{gathered}\end{gathered}

<h3><u>Verification</u> : </h3>

To verify, we'll add all angles of triangle and check the sum of triangle is 180⁰ or not.

{\twoheadrightarrow{\sf{ \:  \: Sum \:  of \:  interior  \: angles = {180}^{0}}}}

{\twoheadrightarrow{\sf{ \:  \: {80}^{0} + {55}^{0} + {45}^{0}= {180}^{0}}}}

{\twoheadrightarrow{\sf{ \:  \: {135}^{0} + {45}^{0}= {180}^{0}}}}

{\twoheadrightarrow{\sf{ \:  \:{180}^{0}= {180}^{0}}}}

\star \:  \: {\underline{\boxed{\tt{\red{LHS = RHS}}}}}

Hence Verified!

During a sale, 20-cent candy bars were sold at 3 for 50 cents. How much is saved on 9 bars?
Mazyrski [523]

Answer:

Step-by-step explanation:

$0.30

Step-by-step explanation:

1 bar of candy = $0.20

3 bars of candy = $0.50

To solve, multiply for both:

If you pay for each candy bar individually, they each cost $0.20. Multiply 9 with 0.20:

9 x 0.20 = $1.80

If you pay for the candy bars by 3's, they cost $0.50 each pack. Divide 9 with 3, then multiply by 0.50:

9/3 = 3

3 x 0.50 = $1.50

Subtract the total cost of the individual from the pack:

$1.80 - $1.50 = $0.30

. $0.30 is your answer.

The class scores of a history test have a normal distribution with a mean Mu = 79 and a standard deviation Sigma = 7. If Opal’s
storchak [24]

The value of z score for the history class test of Opal’s test score is negative one (-1).

<h3>What is normally distributed data?</h3>

Normally distributed data is the distribution of probability which is symmetric about the mean.

The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.

The z score for the normal distributed data can be given as,

Z=\dfrac{X-\mu}{\sigma}

The mean value of the scores of history class is,

\mu=79

The standard deviation value of the scores of history class is,

\sigma=7

Here, the test score of the Opal’s is 72. Thus the z score for her test score can be given as,

z=\dfrac{72-79}{7}\\z=-1

Hence, the value of z score for the history class test of Opal’s test score is negative one (-1).

Suppose that y varies inversely with x.Write an equation for the inverse variation Y=4 when x=7
myrzilka [38]

Answer:

If y varies inversely as x, then we write it as:

y = k/x


where k is some constant.


If we multiply both sides of this equation by x we get an equation for k:

k = x*y


We are given that y=4 when x=7, therefore:

k = 7*4 = 28


Put this back into our original equation to get:

y = 28/x

A friend is in 5th grade math and asks you to explain exponents with example. What do you say?
Vesnalui [34]

Answer:

If my friend is in 5th grade and they need an example on exponents I would show them something like this 7 to the 3 power would be equal to 7 times 7 times 7 which also equals 343 or 4 to the 4th power would be equal to 4 times 4 times 4 times 4 which equals 256

Step-by-step explanation:

This is a simpiler way to show a younger student how to figure out exponents also. Have a great day :D  

If you need help me and my older brother both share this account.
