Question

Which equation is correct regarding the measure of (angle 21)?

a. (angle m₂1 = (a-c)/6-0)
b. (angle m₂1 = (a + c)/(b + c))
c. (angle m₂1 = (6-0)/(b + c))
d. (angle m₂1 = (a + c)/6-0)

Answer 1

The correct equation regarding the measure of angle 21 is (angle m₂1 = (a-c)/6-0). Angle m₂1 is approximately equal to 2.24°.

Step-by-step explanation:

The correct equation regarding the measure of angle 21 is option (a): (angle m₂1 = (a-c)/6-0).

Let's break down the equation: (a-c)/6-0.

Here, 'a' represents the measure of angle 20₁, and 'c' represents the difference between 0₂ and 0₁. Angle 20₁ is given as 29°, and the difference between 0₂ and 0₁ is given as 30.05° - 14.5° = 15.56°. Substituting these values into the equation, we get (29° - 15.56°)/6 - 0 = 13.44°/6 = 2.24°.

Therefore, angle m₂1 is approximately equal to 2.24°.
