Answer 2

Answer:

x = 15

Step-by-step explanation:

♤ Given :

• The ratio of unknown angle as 2x and 3x
• Value of a corresponding angle as 75° .

♤ To find :

• The value of x .

♤ Basic Concept Used

• The pair of corresponding angles are equal .

♤ Procedure

• From our concept we can conclude that :

3x + 2x = 75° [Because corresponding angles are equal]

Solving the obtained equation :

3x + 2x = 75°

5x = 75°

x = 75/5

☆ x = 15 ☆

♤ Verification

• According to our concept used the value of 3x + 2x should equal to 75 .
• We know the value of x as 15 . so lets imply .

3x + 2x = 75°

3(15) + 2(15) = 75

45 + 30 = 75

75 = 75 .
