Could someone please help me with this?

Mathematics
1 answer:
hoa [83]3 years ago

Answer:

We know that the interior angles of any triangle equal 180. Therefore in the left triangle, C must equal 53 in order for the interior angles to equal 180° (65+62+53)

Since these triangles are equal they are congruent. Congruent triangles share the same angles. Therefore C is equal to G. If c is 53 then m<G is also 53. x=53

Additionally, the side lengths of congruent triangles are equal. Therefore 11 is equal to x-y

x is 53 so 53-y=11

-y=-42

y=42

x=53

Step-by-step explanation:

An equation parallel and perpendicular to 4x+5y=19
mestny [16]

Answer:

An equation parallel to 4x + 5y = 19 would be y = -4/5x +12.

An equation perpendicular to 4x + 5y = 19 would be y = 5/4x + 10.

Step-by-step explanation:

The equation given represents a linear equation in Standard Form (Ax + By = C).  Lines that are parallel to each other go the same direction and don't touch, so their slopes must be the same.  However, lines that are perpendicular go in opposite directions and intersect, so their slopes must be the direct opposite of each other.  In order to find the slope, you must first convert from the Standard Form given to Slope Intercept Form (y = mx +b).  When you solve the given equation for 'y', you get: y = -4/5x + 19, where the slope = -4/5.  To make a parallel equation, simply keep the same slope and choose a different y-intercept ('b').  To make a perpendicular equation, take the direct opposide of your slope 5/4 (positive) and choose a different y-intercept.

How many solutions are there for the system x^2+4y^2=100 and 4y-x^2=-20
never [62]
There are 5 solutions for this system.

x^2 + 4y^2 = 100  ____1
4y - x^2 = -20  ____2
Add both 1 & 2 together. x^2 gets cancelled
4y^2 + 4y = 80   (send 80 to the other side and divide by 4)
Then equation the becomes : y^2 + y -20 =0
Now factorise the equation: (y+5) (y-4) = 0
Solve for y :  y = -5 and y = 4
Using the values of y to find the values of x. From equation 1:
x^2 = 100 - 4y^2    x = /100 - 4y^2  (/ means square root) Replace values of y
y = -5, x = /100 - 4(-5)^2 = /100 - 100 = 0
y = 4, x = /100 - 4(4)^2 = / 100 - 64 = /36 = -6 or 6
Thus we have 6 solutions y = -5, 4 and x = -6, 0, 6

13. Xavier spent $84 on art supplies. The canvas for each of his paintings is an additional $1. He
sergeinik [125]

Answer: 84 = 8p - 1 (or $84 = $8p - $1, but it is usually put together like the first equation)

Step-by-step explanation: $84 is the break even point, so the equation must be able to come out to at least $84 if it is correct.

$84 in equation is break even

8p/$8p is the price per painting

-1/-$1 is the addition from the canvas
