Because both lines DE and XY are parallel to one another, the 115° will be same for the line segment. XY
And because XY is a flat line, it's a straight angle. Meaning it's an 180° angle.
We need to find a value of x that when added 115° will equal 180°.
We can use this equation: x + 115 = 180
Subtract both sides 115.
x + 115 - 115 = 180 - 115
x = 65
So, x is equal to 65 degrees.
Answer:
8 1/30
Step-by-step explanation:
Calculate by converting into improper fractions.
Answer:
Step-by-step explanation:
20% discount is 1/5 x 68 = 13.60
So pre-tax price is 68 - 13.60 = 54.40
Add sales tax:
54.40 x 1.06 = 57.66
so the answer is C
Answer:
<h2>m∠ABD = 20°</h2>
Step-by-step explanation:
If m∠ABC = 40° and BD is the bisector of ∠ABC, then
(1) m∠ABD = m∠DBC
(2) m∠ABC = m∠ABD + m∠DBC
From (1) and (2) we have:
m∠ABC = 2m∠ABD
Therefore
2m∠ABD = 40° <em>divide both sides by 2</em>
m∠ABD = 20°
Answer: C (AngleMRN and AngleNRO)
Step-by-step explanation:
A linear pair of angles is formed when two lines intersect. Two angles are linear if they are adjacent angles (angles next to each other) 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.
AngleMRN and AngleNRO together is 180 degrees
I'm not very good at explaining but hope this helps ! :)
