Find m∠ABC = 7x - 4 and m∠BDC = 9x - 1 and and m∠ABC = 107°, find x, m∠ABC and m∠BDC.
Artyom0805 [142]

Answer:

m<BDC = 62 degrees

Step-by-step explanation:

Using the expression;

<ABC = <ABD + <DBC

107 = 7x-4 + 9x - 1

107 = 16x-5

16x = 107 + 5

16x = 112

x = 112/16

x = 7

Get m<DBC

m<BDC = 9x - 1

m<BDC = 9(7)-1

m<BDC = 63 - 1

m<BDC = 62 degrees

ABCD-is-a-parallelogram-P-and-Q-are-two-points-on-the-diagonal-BD-such-that-DP-QB-Prove-that-APCQ-is-a-parallelogram?
Amanda [17]

A quadrilateral in which both pairs of opposite sides are parallel is called a <u>Parallelogram</u>

Step-by-step explanation:

A quadrilateral is said to be  parallelogram if

  • If its opposite sides are equal
  • If the  opposite angles are equal
  • If the diagonals bisect each other
  • If  a pair of opposite sides is equal and parallel.

From the question given above

<u>ABCD is a parallelogram and P and Q are points on BD such that</u>

<u>DP=QB</u>

In ΔAPD and ΔCQB,--------------------------(i)

DP = QB (Given)

∠ADP = ∠CBQ (Alternate interior angles)

AD = BC

(Hence it is proved that -Opposite sides of a parallelogram are equal)

so, ΔAPD ≅ ΔCQB    (As per  SAS congruence rule)

 If , ΔAPD ≅ ΔCQB.-------------------------(ii)

AP = CQ               ( by CPCT )

 In ΔAQB and ΔCPD,-----------------------(iii)

BQ = DP (Given)

∠ABQ = ∠CDP (Alternate interior angles)

AB = CD  (Opposite sides of a parallelogram)

so, ΔAQB ≅ ΔCPD                       (As per  SAS congruence rule)

(iv) AQ = CP              (According to  CPCT as ΔAQB ≅ ΔCPD.)

 From (ii)  and (iv) equation ,we can say that

AP=CQ ,

AQ=CP

<u> It is proved that APCQ has equal opposite sides also it has equal opposite angles. </u><u>Hence,APCQ is a Parallelogram</u>
