70°
Therefore, the complementary angle of 20° is 70°.

What is complement of 2x?

X=180-2X. X+2x=180. 3x=180. So X=60. The complementary angle is 90-60 = 30degrees.

What is the complement of 40⁰?

As the given angle is 40 degrees, then, Complement is 50 degrees.

What is the supplement of a 20 Z angle?

160˚ angle
To solve this, subtract 20 from both sides. Hence, the supplement of a 20˚ angle is a 160˚ angle. This can be proven again, since 20+160=180 , and supplementary angles have a sum of 180˚ .

What is Ξ in sets?

ξ’ = The set of those elements which are not in ξ. = empty set = ϕ Therefore, ξ = ϕ so the complement of a universal set is an empty set. (b) A set and its complement are disjoint sets. Let A be any set then A’ = set of those elements of ξ which are not in A’.

What is the complement of 45?

The complement of 45° is the angle that when added to 45° forms a right angle (90° ).

What is the supplement of 22 degrees?

180°
The supplement of 22° is the angle that when added to 22° forms a straight angle (180° ).

What is the complement of 50?

The complement of 50° is the angle that when added to 50° forms a right angle (90° ).

What is the complement of 40.5 *?

Answer: complement angles add to 90 degrees and supplement angles add to 180 degrees. complement angle to 40 degrees is 90 – 40 = 50 degrees and the supplement angle to 40 degrees is 180 – 40 = 140 degrees.

What is supplement and complement?

Supplementary angles are two angles that have a sum of 180°. Complementary angles are two angles that have a sum of 90°. To determine the supplement, subtract the given angle from 180. 180 – 43 = 137° The supplement of 43° is 137°. To determine the complement, subtract the given angle from 90.

What is the measure of the supplement of 20 degrees?

160∘
⇒ Supplementary angle of 20∘ is equal to 160∘.

What are supplementary angles and complementary angles?

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.
