The sum of three times of x and 11 = 3x + 11 The sum of three times x and 11 is 32 3x + 11 = 32 3x = 32 - 11 3x = 21 x = 21/3 = 7

Three Times x = 3x The sum of three time of x and 11 = 3x + 11 The sum of three times X and 11 is 32 3x + 11 = 32 3x=32-11 3x=21 x=21/3=7

Three times x = 3x

The sum of three times of x and 11 = 3x + 11

The sum of three times x and 11 is 32

3x + 11 = 32

3x = 32 - 11

3x = 21

x = 21/3 = 7

To find complementary angle you only need to subtract the number with 90. Answer: Sum of complementary angle is 90° Then, 90-37 =53°

1Thank You

Yogita Ingle 4 years, 11 months ago

Let the complement be x

Sum of complementary angles is 90^∘

⇒x+37^∘=90∘

⇒x=90^∘−37^∘

= 53^∘

Yogita Ingle 4 years, 11 months ago

It is obvious that Sushant will more part of the book in more time. Here

is the answer of the question.

In 1 hour Sushant reads the part of the book = 1/3

In 11/5 hours Sushant will read part of the book = (1/3) × 11/5

= 11/15 part of the book

Hence, Sushant will read 11/15 part of the book in 11/5 hours.
