<h3>Explanation -:</h3>

In this question we are provided with the two angles that is 8x - 3 and 4x + 3 respectively. It is also given that the sum of this two angles is 180°.

To solve this question we will combine the like terms and there sum must be 180°.

\small\sf{ 8x - 3 + 4x + 3 = 180°}

\bull \: \small\sf{ We \:  will \:  cancel \:  3  \: because \:  they \:  are  \: of \:  opposite \:  signs }

\small\rm 8x  + 4x = 180 \degree

\bull  \: \small\sf{Addition}

\small\rm{ 12x = 180 \degree}

\bull \:  \small\sf{ Divide\: both \: side \: by \: 12}

\small\rm{ \dfrac{12x}{12} =  \dfrac{180}{12}  \:  = 15  \degree}

\small \underline{ \boxed{\sf{x = 15} }}

Answer:

Step-by-step explanation:

Remark

They are asking you to combine like terms. The total should be 180.

Givens

2 angles

  • 8x - 3
  • 4x + 3

Total 180

Solution

8x - 3 + 4x + 3 = 180        The threes cancel. So add what's left. They are of opposite signs, so they cancel.

12x = 180                           Divide both sides by 12

12x/12 = 180 /12                        

x = 15

The answer is y = +8

Explanation:
Since they tell us what x equals (3), let's plug that into the equation

y = (3) + 5

Now, we can just add 3 and 5 together, which we get 8

y = +8

Answer:

∠ A ≅ ∠ E

∠ K = 60°

Step-by-step explanation:

Part 1.

Given that ABCD ≅ EFGH.

Whenever a quadrilateral is congruent to another, and we write the congruency in symbol, then the order of congruency with respect to angles and sides are maintained in the symbol.

That means if ABCD ≅ EFGH, then ∠ A ≅ ∠ E, ∠ B ≅ ∠ F and so on.

Therefore, in this case, ∠ A ≅ ∠ E (Answer) {It is also shown in the diagrams}

Part 2.

Given that, Δ EFG ≅ Δ KLM

Hence, ∠ E ≅ ∠K, ∠ F ≅ ∠ L, and ∠ G ≅ ∠ M

It is also given that ∠ F = 35° and ∠ G = 85°

So, ∠ E = 180° - ∠ F - ∠ G = 180° - 85° - 35° = 60°

Since, ∠ E = ∠ K,

So, ∠ K = 60°. (Answer)
