Respuesta :
A linear pair of angles forms a straight line, so it's another way of saying that they are supplementary or add to 180 degrees.
So, one angle is: 2x - 3
where the other one is: "x"
Add those 2 together, set the sum equal to 180, and then solve for "x".
Answer:
∠ABD = 61° and ∠DBC =119°
Step-by-step explanation:
Linear Pair: Two adjacent angles are said to form a linear pair angles , if their non-common arms are two opposite rays.
The sum of adjacent angles is 180°.
Refer the attached figure
Let ∠ABD be x
Since we are given that In a certain linear pair, one angle measures three less than twice as much as the other.
So, ∠DBC = 2x-3
Since ∠ABD and ∠DBC are linear pairs
So, ∠ABD + ∠DBC =180°
[tex]x+2x-3=180^{\circ}[/tex]
[tex]3x-3=180^{\circ}[/tex]
[tex]3x=183[/tex]
[tex]x=\frac{183}{3}[/tex]
[tex]x=61[/tex]
So, ∠ABD = 61°
Now ∠DBC = 2x-3 = 2(61) -3 =119°
Hence ∠ABD = 61° and ∠DBC =119°
Refer the attached figure.
