Suppose the supplement of the angle is x degrees.
Then the angle is 180 - x degrees.
Therefore the complement of the angle is 90 - (180 - x) degrees = x - 90 degrees.
So 5*(x - 90) - 2*x = 40
Solve the above equation for x.
Supplementary angles add up to 180° Complementary angles add up to 90° Let the angle be θ; then form an equation from the known facts: 1) Supplement: 180° - θ 2) Complement: 90° - θ → twice complement is (90° - θ) × 2 → increased by 65° is (90° - θ) × 2 + 65° These two are equal, thus: 180° - θ = (90° - θ) × 2 + 65° → 180° - θ = 180° - 2θ + 65° → θ = 65° The angle is 65°.

An equation is a mathematical statement that may (or may not) be true, defined for some variables. Solving an equation is finding those values of the variables for which the equation or statement is true.

An equation is a true statement. [ 75 + 4 = -2 ] is a false statement.
The measure of an angle whose complement is four ninths its supplement?æ is 18 degrees. It is calculated as follows: let y be the angle, its complement will be (90-y) degrees and its supplement will be (180-y)?æ degrees and?æ since it complement is?æ 4/9 its supplement; then?æ it is?æ?æ(90-y)= 4/9(180-y).?æ Hence, you will get 18 degrees when you solve the equation.
Supplementary angles add up to 180° Complementary angles add up to 90° Let the angle be θ; then form an equation from the known facts: 1) Supplement: 180° - θ 2) Complement: 90° - θ → twice complement is (90° - θ) × 2 → increased by 65° is (90° - θ) × 2 + 65° These two are equal, thus: 180° - θ = (90° - θ) × 2 + 65° → 180° - θ = 180° - 2θ + 65° → θ = 65° The angle is 65°.
Very simple, let's mount a linear system: x=measure of the angle; y=supplement; z=complement: I:x+y= 180; II:x+z= 90; III: y+z= 150; Summing I with II we have: I+II: 2x+y+z= 270; III: y+z=150 Now, subtracting III from I+II we have a simple equation: 2x=120; >x= 60< So, the angle whose sum of the measures of its complements and supplement is 150, has 60 degrees.

A solution or root makes a true statement when substituted in an equation.
An equation is a mathematical statement that may (or may not) be true, defined for some variables. Solving an equation is finding those values of the variables for which the equation or statement is true.
That's an equation.

No, it is not a true statement. It is a false statement.
An equation is a true statement. [ 75 + 4 = -2 ] is a false statement.
If a statement includes an "equals" sign ( = ) then the statement is an equation. By the way . . . it may or may not be a true statement. "10 equals 120" is not true.
