In the paper airplane shown
Murrr4er [49]

Answer:

∠GHE = 55°

Step-by-step explanation:

ABCD is a quadrilateral (4 sided figure). We know that the sum of the interior angles (4 angles) of a quadrilateral in 360°.

Thus, A + B + C + D = 360

<em>we know b = c = 90 and a = 125, thus we can find D.</em>

<em>125 + 90 + 90 + D = 360</em>

305 + D = 360

D = 360 - 305 = 55°

<u>Note:</u> since Quadrilateral ABCD is congruent to Quadrilateral EFGH, then the measure of D is equal to measure of H (Angle GHE). Thus

∠GHE = 55°

2nd answer choice is correct

In 3-4 sentences, describe how you would find a line parallel to the line 2x + 5y = 15 that goes through the point (-10, 1). Be
larisa86 [58]

the parallel line is 2x+5y+15=0.

Step-by-step explanation:

ok I hope it will work

soo,

Solution

given,

given parallel line 2x+5y=15

which goes through the point (-10,1)

now,

let 2x+5y=15 be equation no.1

then the line which is parallel to the equation 1st

2 x+5y+k = 0 let it be equation no.2

now the equation no.2 passes through the point (-10,1)

or, 2x+5y+k =0

or, 2*-10+5*1+k= 0

or, -20+5+k= 0

or, -15+k= 0

or, k= 15

putting the value of k in equation no.2 we get,

or, 2x+5y+k=0

or, 2x+5y+15=0

which is a required line.

The line represented by the equation 4y + 2x = 33.6 shares a solution point with the line represented by the table
mamaluj [8]

Answer:

The solution of this system is

(4). (6.0,5.4)

Step-by-step explanation:

First we have to find the equation of the line represented in the table; for that we have to find it's slope m and it's y-intercept b and then write it in the following form:

y=mx+b

The slope m of the line we get from first two points:

m=\frac{3.8-3.2}{(-2)-(-5)} =0.2

thus we have

y=0.2x+b

we find b by putting the point (2,4.6) into the function:

4.6=0.2(2)+b

b=4.6-0.4=4.2

Thus we have

y=0.2x+4.2

Now we have to find where this line intersects with 4y+2x=33.6; to do this we just substitute y with y=0.2x+4.2:

4(0.2x+4.2)+2x=33.6

0.8x+16.8+2x=33.6

\boxed{x=6 }

<em>We have the x-coordinate of  the intersection.</em>

We find the y-coordinate by substituting x=6 into y=0.2x+4.2:

y=0.2(6)+4.2=5.4

\boxed{y=5.4}

Thus the solution to the system is

\boxed{(x,y)=(6, 5.4)}

which is option 4.
