Answer:
No, it is not a right triangle.
Step-by-step explanation:
Given:
The sides of the triangle = 15 10 and 7
To Find:
Whether the triangle is a right triangle = ?
Solution:
According to Pythagorean theorem , In an right triangle the the sum of the squares of the two smaller sides must equal to the square of the larger side
where
a and b are the smaller sides
c is the larger side
Now from the given data, lets assume
a = 10 and b =7 and c =15
Substituting in the above equation we get,
100 + 49 = 225
149 = 225
So, the given triangle is not a right triangle.
The opposite of 4.5 is -4.5
The opposite of -5.4 is 5.4
The opposite of -1.3 is 1.3
The opposite of 3.2 is -3.1
Therefore your answers are,
4.5 C)
-5.4 A)
-1.3 D)
3.1 B)
Answer:
B and C
Step-by-step explanation:
The denominator of the rational expression cannot be zero as this would make it undefined.
Equating the denominator to zero and solving gives the values that x cannot be.
solve
3x² - 75 = 0 ( add 75 to both sides )
3x² = 75 ( divide both sides by 3 )
x² = 25 ( take the square root of both sides )
x = ± = ± 5 → B and C
Answer:
B
Step-by-step explanation:
not an arithmetic sequence
d=18-10=8
d=25-18=7
d not equal
