Answer:

  • x = 34°
  • y = 35°

Step-by-step explanation:

The questioner asks for the values of 'x' and 'y' which are measures of angles in parallelogram ABCD.

Before getting the solution, one needs to be aware of the following properties a parallelogram has :

  • Opposite sides are equal.
  • Opposite angels are equal.
  • Consecutive angles are supplementary.

We need to apply the above mentioned properties to get the solution.

∠A and ∠B are concecutive angles. So, their sum is 180°

  • ∠A = 3y°
  • ∠B = (2y - 5)°

\longrightarrow 3y + (2y - 5) = 180

\longrightarrow 5y - 5 = 180

\longrightarrow 5y = 180 - 5

\longrightarrow 5y = 175

\longrightarrow y = \sf{\dfrac{175}{5}}

\longrightarrow y = 35°

Measure of y = 35°

Measure of ∠A

\longrightarrow ∠A = 3(35)

\longrightarrow ∠A = 105°

∠A and ∠C are opposite angles. So, their measure will be same.

  • ∠C = 105°

\longrightarrow 3x + 3 = 105

\longrightarrow 3x = 105 - 3

\longrightarrow 3x = 102

\longrightarrow x = \sf{\dfrac{102}{3}}

\longrightarrow x = 34

Measure of x = 34°

Therefore, the measure of x and y is 34° and 35° respectively.

\huge\bold{Given}

∠A = (3y°)

∠B = (2y - 5)°

∠C = (3x + 3)°

\huge\bold{To  \: Find}

Value of (x) and (y).

_________...

Here,

∠A + ∠B = 180° (Since they are adjacent angles)

According to the Question:-

∠A + ∠B = 180°

→ (3y°) + (2y - 5)° = 180°

→ 3y° + 2y° - 5° = 180°

→ 5y° = 180° + 5°

→ y° = 185°/5

→ y° = 37°

NOW, finding value of (x) :-

Also,

∠B + ∠C = 180° (Since they are adjacent angles)

So,

(2y - 5)° + (3x + 3)° = 180°

→ [2(37) - 5]° + (3x + 3)° = 180°

→ [74 - 5]° + 3x° + 3° = 180°

→ 69° + 3° + 3x° = 180°

→ 72° + 3x° = 180°

→ 3x° = 180° - 72° = 108°

→ x° = 108°/3

→ x° = 36°

∴ x = 36°

∴ x = 36°& y = 37°.
