Solve this parallelogram angle

Mathematics
2 answers:
Vesnalui [34]2 years ago

Answer:

103

Step-by-step explanation:

angles formed on the same line of a parallelogram are supplementary angles

( the angle with the measure of 77 degrees and the angle labeled "x" are formed on the same line which means they are supplementary )

supplementary angles add up to equal 180

hence, 77 + x = 180

180 - 77 = 103

Hence, x = 103

Let the numbers be n, n+2, n+4

Sum equals too= 13+2(n+4), which is 2n+21

a) Equation--> n+n+2+n+4= 2n+21

b) Solution--> 3n+6= 2n+21

                      => n= 15

c) Second number--> 17 (15+2)

   Third number--> 19 (15+4)

d) 15+15+2+15+4=30+21

   => 51= 51

So, the equation is true.

Place the correct symbol, &lt; or &gt;, between the two numbers 11/18 17/24
evablogger [386]

For this case we must indicate the correct sign between the following numbers:

\frac {11} {18}\ and\ \frac {17} {24}

We have to:

\frac {11} {18} = 0.611111111111\\\frac {17} {24} = 0.708333333333

So, we have to \frac {17} {24}> \frac {11} {18}

Answer:

\frac {17} {24}> \frac {11} {18}

If f ( x ) = 3x² - 5x + 7 , Show that f ( -1 ) = 3 f ( 1 ) .<br><br><br><br><br>Tysm :')​
Lelechka [254]

Solution :

  • 3x² - 5x + 7

put x = -1

  • 3(-1)² - 5(-1) + 7

  • 3(1) + 5 + 7

  • 3 + 12

  • 15

Now, put x = 1

  • 3(1)² - 5(1) + 7

  • 3(1) - 5 + 7

  • 3 + 2

  • 5

here :

  • f(-1) = 15

  • f(-1) = 3(5)

  • f(-1) = 3 f(1)
