Question

please do solve my question pls its urgent​

Answer 1

Answer:

54 degrees

Step-by-step explanation:

let one of the complimentary angles be x

⇒other angle=90-x

Given,

one angle is two-third of the other

To find x.

2x/3=90-x

⇒2x=3(90-x)

⇒2x=270-3x

⇒2x+3x=270

⇒5x=270

⇒x=270/5

⇒x=54 degrees

Answer 2

Answer:

Step-by-step explanation:

Solution:                                

As we know that a complementary angle = 90°

Let,

    One of the angles = x , then

    Other angle = 2/3x

    So,

       ⇒2/3x+x=90°

      ⇒2x+3x/3=90°

      ⇒ 5x/3=90°

      ⇒ 5x=90°×3

      ⇒5x=270°

      ⇒x=270°/5

      ⇒x=54°

     So,

      1st angle=54°

      2nd angle=2/3×54°

                      =2×18°

                      =36°

                       OR,

     2nd angle = 90°-54°

                      = 36
