Evaluation of the expression using order of operation gives 26/11.

How to evaluate the expression

Given 13 ÷(2.5-1-3).33 =  13 ÷ 33( 2 x 5 - 1 - 3)

To evaluate this expression we need to apply the order of operation rule, BODMAS or PEMDAS.

13 ÷(2.5-1-3).33 =  13 ÷ 33( 2 x 5 - 1 - 3)  Evaluate multiplication

                         = 13 ÷ 33(10 - 1 - 3)        Evaluate what is in the bracket

                        =   13 ÷ 33(6)                  Evaluate division

                        = 13/33 x 6

                        = 78/ 33 = 26/11

Therefore, evaluating the expression gives 26/11.

The following is an incomplete paragraph proving that the opposite sides of parallelogram ABCD are congruent:
Semmy [17]

Answer:  Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem.

Step-by-step explanation:

Given : ABCD is a parallelogram.

That is, AB ║ CD and AD ║BC

We have to prove that: AB≅CD and AD≅BC

Proof:

Construct diagonal AC in the parallelogram ABCD.

Since, AC ≅ AC ( reflexive)

∠ BAC ≅ ∠ DCA  ( By the alternative interior angle theorem)

∠ BCA ≅ ∠ DAC   ( By the alternative interior angle theorem)

⇒ Δ BCA ≅ Δ DAC ( By ASA congruence postulate )

⇒ AB≅CD as well as AD≅BC ( BY CPCTC )

Thus, the opposite side of the parallelogram are congruent.

Consider all angles whose reference angle is 45° with terminal sides not in Quadrant I.The angles that share the same cosine val
Oksana_A [137]

Solution:

As we know reference angle is smallest angle between terminal side and X axis.

As cosine 45 ° is always positive in first and fourth quadrant.

i.e CosФ, Cos (-Ф) or Cos(2π - Ф) have same value.

As, Cos 45°, Cos (-45°) or Cos ( 360° - 45°)= Cos 315°are same.

So, Angles that share the same Cosine value as Cos 45° have same terminal sides  will be in Quadrant IV having value Either Cos (-45°) or Cos (315°).

Also, Cos 45° = Sin 45° or Sin 135° i.e terminal side in first Quadrant or second Quadrant.
