Multiple choice maths complementary angle, supplementary angles and adjcent angles acute and obtuse angles types of angle measurement of an angle

Find the angles in each of the following.
The angle whose complement is one sixth of its supplement

  1. $72^{\circ}$
  2. $32^{\circ}$
  3. $62^{\circ}$
  4. None of these

A Correct answer
Explanation

Let the angle be $x^0$.


Supplement angle $=(180^0-x)$

Complement angle $=(90^0-x)$

According to the question,
$\dfrac{1}{6}\times (180^0-x)=(90^0-x)$

$(180^0-x)=6(90^0-x)$

$180^0-x=540^0-6x$

$5x=360^0$

$x=72^0$


Hence, this is the answer.

Find the angles in each of the following.
The angle which is four times its supplement

  1. $144^{\circ}$
  2. $44^{\circ}$
  3. $14^{\circ}$
  4. None of these

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Let the angle be $x^0$.


According to the question,
Supplement angle $=(180^0-x)\times 4$

So,

$x=720^0-4x$

$5x=720^0$

$x=144^0$


Hence, this is the answer.

Find the angles in each of the following.
The angles whose supplement is four times its complement

  1. $60^{\circ}$
  2. $30^{\circ}$
  3. $120^{\circ}$
  4. None of these

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Let the angle be $x^0$.


Supplement angle $=(180^0-x)$

Complement angle $=(90^0-x)$

According to the question,
$180^0-x=4(90^0-x)$

$180^0-x=360^0-4x$

$3x=180^0$

$x=60^0$


Hence, this is the answer.

Multiple choice maths complementary angle, supplementary angles and adjcent angles acute and obtuse angles types of angle measurement of an angle

Find the angles in each of the following.
The angle which is two times its complement

  1. $60^{\circ}$
  2. $120^{\circ}$
  3. $30^{\circ}$
  4. None of these

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Let the angle be $x^0$.


According to the question,
Complement angle $=(90^0-x)\times 2$

So,

$x=180^0-2x$

$3x=180^0$

$x=60^0$


Hence, this is the answer.
