Answer:
Two points are collinear when they lie on the same line. Points are collinear but not lines. Rather when two lines lie on the same plane we say they are coplanar.
Hence, line AB and CD are NOT collinear, so they are noncollinear and they are coplanar.
Two or more lines are said to be intersecting, when the lines meet at some point, when lines are not intersecting they are said to be parallel.
Recall that one of the properties of a rectangle is that opposite sides are parallel.
Notice that line AB and CB are the opposite sides of the rectangle ABCD.
Thus, line AB and CD are not intersecting but are parallel.
Therefore, the terms that best describe lines AB and CD are
parallel
noncollinear
coplanar
Step-by-step explanation:
For 3, it is an isosceles triangle and it is an acute triangle.
Solution:
<u>Note that:</u>
- Given angles: w + 8° and 48°
- w + 8 + 48 = 180
<u>Solve for w in the equation "w + 8 + 48 = 180".</u>
- => w + 8 + 48 = 180
- => 56 + w = 180
- => w = 180 - 56
- => w = 124°
The value of w is 124.
So from 100% you increased it by 30% to become 520
130%=540
percent means parts out of 100
130%=130/100=1.3
1.3 of whole=520
divide both sides by 1.3
whole=400
the number was 400
Answer:
25.1 in (nearest tenth)
Step-by-step explanation:
<u>Formula</u>
Circumference = πd (where d is the diameter)
From inspection of the diagram:
⇒ Circumference = 8π
= 25.1 in (nearest tenth)
