Answer:

B. Sum of interior angles; converse of opposite angles theorem

Step-by-step explanation:

In statement 1, all the interior angles of the quadrilateral are added to give a sum of 360°. The reason would therefore be "sum of interior angles".

As a follow up to the already established fact that the opposite angles of the quadrilateral are congruent to each other, this satisfies the Converse of Opposite Angles Theorem, which states that if the opposite angles of a quadrilateral are congruent to each other then the quadrilateral must be a parallelogram.

Reason for the statement in number 6 is definitely "converse of opposite angles theorem."

Find two numbers, if … b Their sum is −7 and their difference is 14

Delicious77 [7]

Answer:

x=0

y=-21/7

Step-by-step explanation:

Let the two unknown be x and y

x+y=-7...(1)

x-y=14...(2)

From (1) make x the subject of formula

x=-7-y...(3)

Substitute (3) into (2)

-7-y-y=14

-7-2y=14

Add 7 to both sides

-2y=21

Add both sides by-2

y=-21/2

Substitute the value of y into (3)

x=-7-(-21/2)

x=-7+21/3

Lcm

x=-21+21/3

x=0/3

x=0

The H.C.F and the LCM of two numbers are 36 and 720 respectively. If one of the numbers is 180, which is the other number. *

lutik1710 [3]

Answer:

let p(x)=180

LCM=720

HCF=36

WE HAVE TO FIND q(x)=?

as we know that

p(x)×q(x)=LCM×HCF

NOW WE HAVE TO FIND q(x)

q(x)=LCM×HCF/p(x)

q(x)=720×36/180

q(x)=25920/180

q(x)=144

i hope this will help you
