Step-by-step explanation:

Which of the following is a solution of the system 2x + y = 9 and 3x + 5y = 19.​

Answers

2x+y=9

3x+5y=19

I will do this problem in 2 ways. I.)Substitution II.)Elimination

Solution I.) Substitution

We can subtract 2x from both sides in the first equation.

y=9-2x

Now we can substitute the y in the second equation with 9-2x

3x+5(9-2x)=19

-7x+45=19

-7x=-26

x=26/7

y=9-2(26/7)=11/7

Solution II.)Elimination

We can multiply both side of first equation by 5 to get a 5y in both equations.

10x+5y=45

Now because both are positive 5y we just need to do simple subtraction of the 2 equation, each side respectively.

(10x+5y)-(3x+5y)=45-19

7x=26

x=26/7

2*26/7+y=9

y=11/7

Ultimately you get the same answer, both are viable methods, some problems are faster with one method but I recommend mastering both since they are very useful.

Step-by-step explanation:

Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27.  So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

Required

Find tan(30)

Let the side opposite 30 degrees be A and the side adjacent 30 degrees be B

So [using tangent identity]:

[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

This gives:

[tex]tan(30) = \frac{A}{B}[/tex]

Answer:

Step-by-step explanation:

d is on a line with s so they are supplementary d+80 = 180 so d has to be 100

s and h are equal, therefore vertical angle x is also 80

Then 80 + 60 + y = 180 since they are on a straight line so y=40

the value of x?

B. 50
C.90
D. 92

Answers

The answer is B. Hope this helps

The value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.

What is quadrilateral?

It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.

We have:

In the diagram below, OP is circumscribed about quadrilateral ABCD.

In a quadrilateral, the sum of the opposite angles is equal to 180 degree

x + 20 + 110 = 180

x + 130 = 180

x = 50

Thus, the value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.
