Answer:
All Triangles are closed figure polygons that have three straight sides
Step-by-step explanation:
All 2D shapes are plane figures so this one is false. Three right angles are greater than 180 so this is fake. Polygon and closed figures are shapes with three or more closed sides. And triangles have straight sides.
Step-by-step explanation:
k² + 5k + 13 = 0
Using the quadratic formula which is
From the question
a = 1 , b = 5 , c = 13
So we have
<u>Separate the solutions</u>
The equation has complex roots
<u>Separate the real and imaginary parts</u>
We have the final answer as

The probability that jim will win = P(A) = 1/9
<h3>What is probability?</h3>
The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
<h3>According to the given information :</h3>
The odds in favor of jim beating a friend at golf are = 1:8
Let A be the event that Jim beating a friend golf.
So,
according to ratio, it becomes
P(A)/P(A') = 1/8
P(A) = 1x
P(A') = 8x
we know that :
P(A) + P(A') = 1
x + 8x = 1
9x = 1
x = 1/9
so that
P(A) = 1/9
P(A') = 8/9
the probability that jim will win = P(A) = 1/9

Answer:
12
Step-by-step explanation:
This thing to know about this question is that angle 1 and angle 3 are actually the same.
When two lines intersect, the opposite angles such as that shown in 1 and 3 are equal to each other.
So what you can do is set angle 1 and 3 equal to each other like so:
5x+10 = 70
Then solve for x
5x+10 = 70
5x = 60
x = 12
