If two angles are supplementary, then

the sum of their measures is 180°.

So if the measure of an angle is 77°,

the measure of its supplement is 103°.

We can find the measure of its supplement by taking 180 minus the measure of the original angle which in this case is 180 - 77 or 103°.

There is a quadrilateral MNPQ in which side MN is congruent to side PQ and side NP is parallel to side MQ. The diagonal MP and t

8_murik_8 [283]

Answer: QN = 12

Step-by-step explanation: This quadrilateral is a paralelogram because its 2 opposite sides (NP and MQ) are parallel and the other 2 (MN and PQ) are congruent.

In paralelogram, diagonals bisect each other, which means QR = RN.

If QR = RN:

QR = 6

Then,

QN = QR + RN

QN = 6 + 6

QN = 12

The diagonal QN of quadrilateral MNPQ is QN = 12.

Solve the system using elimination, 2x - 3y = - 19 7x + 7y = 21

blagie [28]

Answer:

x = -2

y = 5

Step-by-step explanation:

2x - 3y = -19 ---------------------------(I)

7x+ 7y = 21 -----------------------------(II)

Multiply equation (I) by 7 and equation (II) by 3.Then add and so y will be eliminated and you will get the value of x

(I)*7 14x - 21y = - 133

(II)* 3 21x + 21y = 63 {Now add}

35x = -70

x = -70/35

x = - 2

Plug in x = - 2 in equation (I)

2*(-2) - 3y = -19

-4 - 3y = -19

-3y = -19 + 4

-3y = -15

y = -15/-3

y = 5

Which equation can be used to find the value of x in this figure. I’m so stumped but I think it is c

vitfil [10]

Answer:

$106\°+x=180\°$

Step-by-step explanation:

Observing the figure

we know that

$106\°+x=180\°$ ----> by supplementary angles

Solve for x

$x=180\°-106\°=74\°$
