Answer:

ΔRES ≅ ΔTEQ

Step-by-step explanation:

A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel to each other.

Opposite angles of a parallelogram are equal and the diagonals bisect each other. Each diagonal of a parallelogram separates it into two congruent triangles.

Given parallelogram QRST with diagonals QS and RT intersecting at point E

Therefore, the diagonals divide parallelogram QRST into congruent triangles, hence:

ΔRES ≅ ΔTEQ

<u>Given </u><u>:</u><u>-</u>

  • x/2 = 3

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • The value of 2x + 2 .

<u>Solution</u><u> </u><u>:</u><u>-</u>

The given equation to us is ,

\longrightarrow x/2= 3

\longrightarrow x = 3*2

\longrightarrow x = 6

Now we need to find out ,

\longrightarrow 2x + 2

\longrightarrow 2(6) + 2

\longrightarrow 12 + 2

\longrightarrow 14

Someone pls help im so close
Sliva [168]

Answer:  A) 126.6

<u>Step-by-step explanation:</u>

Since we know ∠B = 85° and ∠C = 53°, we can use the Triangle Sum Theorem (angles of a triangle = 180°) to calculate ∠A.

∠A + ∠B + ∠C = 180

∠A + 85 + 53 = 180

∠A + 138 = 180

∠A = 42

Now we have:

                       A = 42          B = 85       C = 53

                       a = 85          b = ???       c = ???

We have all of the information for ∠A and side a so we can use the Law of Sines to find b (AC).

\dfrac{\sin 42}{85}=\dfrac{\sin 85}{b}\\\\\\b(\sin 42)=85(\sin 85)\\\\\\b=\dfrac{85\sin 85}{\sin 42}\\\\\\b=\large\boxed{126.547}
