Let
x--------> the measure of the adjacent interior angle
y--------> the measure of an exterior angle at the vertex of a polygon
we know that
The measure of the adjacent interior angle and the measure of an exterior angle at the vertex of a polygon are supplementary angles
so
°
<u>Examples</u>
case 1)
<u>In a square</u>
°
so
°
In this case
The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle
case 2)
<u>an equilateral triangle</u>
°
so
°
In this case
The measure of an exterior angle at the vertex of a polygon is not equals the measure of the adjacent interior angle
therefore
<u>the answer is</u>
sometimes
Probability =
(number of different successful results) / (number of all possible results) .
Number of marbles that are not blue = 7
Number of marbles in the bag = 10
Probability that one marble drawn at random is not blue = 7/10 = 70% .
Answer:
Option D is correct.
SAS Congruence Postulates
Step-by-step explanation:
In Δ QRS and Δ TRS
[Side] [Given]
[Common Side] [Given]
[Angle]
SAS(Side- Angle -Side) postulates states states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
Then, by SAS postulates
Answer: 1. F
2. C
3.a
4. E
5. D
6. B
Step-by-step explanation:
Keeping in mind that there are 2000 lbs in 1 ton, and that there are 100 cents in $1.
