What is the greatest number of acute angles that a triangle can contain?
Answers
Answer:
The greatest number of acute angle a triangle can contain are:
3
Step-by-step explanation:
We know that a acute angle is a angle whose measure is less than 90°.
Now we know that the sum of all the angles of a triangle is 180°.
Now we have to find such 3 angles which are less than 90° and add up to 180°.
Let we consider a equilateral triangle.
In a equilateral triangle each angle measures 60°<90°.
and also:
60+60+60=180°.
Hence, the greatest number of acute angles a triangle can contain are:
3.

25 feet
Step-by-step explanation:
Basically that non-regulation tennis court is a rectangle. You want to know the length of the diagonal. If you draw it on paper, you'll see that this then become 2 triangles... of which you have 2 sides, and are seeking the hypotenuse. So....
H² = A² + B²
H² = 20² + 15² = 400 + 225 = 625
H = 25 feet.
Answer:
The diagonal of a non-regulation tennis court = 25 feet
Step-by-step explanation:
Pythagorean theorem
Hypotenuse² = Base² + Height²
The tennis court is like a rectangle.
We can consider the court as made of two right angled triangle
To find the length of diagonal of court
Here base = 15 feet and height = 20 feet
Diagonal or hypotenuse can be written as,
Diagonal ² = Base² + Height²
= 15² + 20²
= 225 + 400
= 625
Diagonal = √625 = 25 feet
Therefore the diagonal of a non-regulation tennis court = 25 feet
Andrew multiples the number by 21 then subtracts the result from 40.
They both finish with the same answer. What was the number?
Answers
Faye squares the number: x²
then multiplies by 2: 2x²
and adds 4: 2x²+4
Andrew multiplies the number by 21: 21x
then subtracts the result from 40: 40-21x
They both finish with the same answer, so the results are equal.
The number is negative so x=-12.
The number is -12.

Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answers
The coordinate (x,y)=(-2,-3).
We have given the following pair of equations
y = 3x + 3.....(1)
y = x − 1.....(2)
Here we use the substitution method
What substitution method?
The value of one variable from one equation is substituted in the other equation
So the given system of linear equation
We have substitute the value of y from equation 2 into the value of y in equation one
So we get
x − 1= 3x + 3
add like terms
x-3x=3+1
-2x=4
x=4/-2
x=-2
Plug x=-2 in equation 2 we get,
y = -2 − 1
y=-3
Therefore we get the coordinate(x,y)=(-2,-3).
