Answer:

The value of x is 108°

Step-by-step explanation:

Given interior angles of parallelogram are:

\frac{2}{3}x, x, \frac{2}{3}x\ and x

<u>The sum of interior angles of a parallelogram is 360°.</u>

We will use this information to find the value of x.

So adding up all the angles and putting the sum equal to 360 we get,

x+\frac{2}{3}x+x+\frac{2}{3}x = 360

2x+\frac{2}{3}x+\frac{2}{3}x = 360\\2x + \frac{4}{3}x = 360

Taking LCM on left side of the equation, as it involves fraction

\frac{6x+4x}{3} = 360\\\frac{10x}{3} = 360

Multiplying both sides by 3

\frac{10x}{3} * 3 = 360 * 3\\10x = 1080

Dividing both sides by 10

\frac{10x}{10} = \frac{1080}{10}\\x = 108

Hence,

The value of x is 108°

The ratio of the perimeters of two rectangles is 4 to 7. The perimeter of the larger rectangle is 42 inches.
adelina 88 [10]
The proportion is 4:7 compared to the proportion ?:42. The way I prefer to do this is 7÷4=1.75. 1.75 is the difference between the smaller and larger rectangles. Then take 42÷1.75=24. The perimeter of the smaller rectangle is D. 24.

ANSWER



The general solution is 86+280n, where n is an  integer



<u>EXPLANATION</u>



In order  to solve the linear congruence;



33x \equiv 38(mod\:280)



We need to determine the inverse of 33 (which is a Bézout coefficient for 33).



To do that we must first use  the Euclidean Algorithm to verify the existence of the inverse by showing that;



gcd(33,\:280)=1



Now, here we go;



280=8\times33+16



33=2\times 16+1



16=2\times 8+0



The greatest common divisor is the last remainder before the remainder of zero.



Hence, the gcd(33,\:280)=1.



We now express this gcd of 1 as a linear combination of  33 and 280.



We can achieve this by making all the non zero remainders the subject and making a backward substitution.



1=33-2\times 16--(1)



16=280-33\times8--(2)



Equation (2) in equation (1) gives,



1=33-2\times (280-8\times33)



1=33-2\times 280+16\times33



1=17\times33-2\times 280



The above linear combination tells us that  17 is the inverse of 33.



Now we multiply both sides of our congruence relation by 17.



17\times 33x \equiv 17\times 38(mod\:280)



This implies that;



x \equiv 646(mod\:280)



x \equiv 86.



Since this is modulo, the solution is not unique because any integral addition or subtraction of the modulo (280 in this case) produces an equivalent solution.



Therefore the general solution is,



86+280n, where n is an  integer
