Which of the following is true for two complementary angles ∠RST and ∠TSU?
Question 4 options:

A)

m∠RST + m∠TSU = 90°

B)

m∠RST + m∠TSU = 180°

C)

m∠RST = m∠TSU

D)

m∠RST = ½ × m∠TSU

Option "A" is the correct answer to the following question.

Step-by-step explanation:

Complementary angles ⇒ If the sum of two angles becomes 90 degrees, we can say that this is a complementary pair of angles.

In the given situation angle ∠RST and ∠TSU are a pair of complementary angles.

∠RST + ∠TSU = 90° (Complementary angles)

So, we say that the option "A" is the correct answer.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
