Answer:
B.
D.
Step-by-step explanation:
By exterior angle theorem:
Answer:
A
Step-by-step explanation:
Given
6 = 25 ( divide both sides by 6 )
=
Take the ln of both sides
ln = ln () , hence
x lne = ln () ← note ln e = 1
x = ln () ≈ 1.43 → A
Answer: 122
Step-by-step explanation: Substitute the values of <em>x</em> and <em>y</em> into the expression.
"Fill in the blanks" with the numbers given for <em>x</em> and <em>y</em>.
Answer:
Linear Pair:
∠ 1 and ∠ 2
Vertical Angles:
∠ 1 and ∠ 3
Supplementary Angles:
∠ 7 and ∠ 6
Step-by-step explanation:
Linear Pair:
A linear pair of angles is formed when two lines intersect.
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Example
∠ 1 and ∠ 2 ∠ 8 and ∠ 5 ,etc
Vertical Angles:
The angles opposite each other when two lines cross.
They are always equal.
Example
∠ 1 and ∠ 3 ∠ 8 and ∠ 6 ,etc
Supplementary Angles:
Two Angles are Supplementary when they add up to 180 degrees.
Examples two angles (140° and 40°)
All Linear pair are Supplementary angles
Example
∠ 7 and ∠ 6 ∠ 8 and ∠ 5 ,etc
