Answers

Answer 1

Answer:

B

Step-by-step explanation:

The size of the exterior angle in a triangle is the sum of interior opposite angles. In this case, it's

Angle ACD=40+40=80° (Exterior angle=sum of int. opp. angles)

Answer 2

Answer:

b. 80°

Step-by-step explanation:

B is 40°

A triangle has 180°

40 + 40 + x = 180

80 + x = 180

x = 100

Since it's a supplementary angle...

180 - 100 = 80

Answers

Answer:

its the first one on the list bc when x is 0 you get f(x) = 1 and thats the only fjnction that does that with all of them.

Answer:

f(x) = - 2x + 1

Step-by-step explanation:

The equation of a linear function in slope- intercept form is

f(x) = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 3) and (x₂, y₂ ) = (2, - 3) ← 2 ordered pairs from the table

m = [tex]\frac{-3-3}{2-(-1)}[/tex] = [tex]\frac{-6}{2+1}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2

The function crosses the y- axis at (0, 1 ) ⇒ c = 1

f(x) = - 2x + 1

Find two consecutive odd integers such that thrice the smaller is 92 more than the larger
Nonsense Answer = Report
Innocent Answer but no Answer = Report
Answer with Solution = Heart, 5 Star, and Brainliest

Answers

Answer:

A = 47

B = 49

Step-by-step explanation:

Let the two consecutive odd integers be A and B

We know that B = A + 2, and that A is odd.

We are also told that

3A - 92= B

Use this last expression for B in the first equation:

B = A + 2

3A - 92 = A + 2

2A = 94

A = 47

B must therefore be 47 + 2 = 49

Check:

1)  A + 2 = B?  YES

2)  3A - 92= B?

    3*47 - 92 = 49?

      141 - 92 = 49   YES

3) Are they both odd consecutive integers?  YES

     

A = 47

B = 49

Morgan drew 3 lines. • Line A moves in the same direction as Line B and the lines never intersect. • Line B forms a perfect right angle (90° angle) with Line C. Which statement is correct about these lines?
A: Line B is parallel to Line
2: Line A is perpendicular to Line B
3: Line C is perpendicular to Line A
4: Line C is parallel to Line A ​

Answers

Answer: line c is perpendicular to line a

Step-by-step explanation:

Parallel lines are two or more lines that lie next to each other

Line C is perpendicular to Line A.

The correct option is 3.

What are parallel and perpendicular lines?

Parallel lines are the lines that do not intersect or meet each other at any point in a plane.

In Mathematics, a perpendicular is defined as a straight line that makes the right angle (90 degrees) with the other line. In other words, if two lines intersect each other at the right angle, then the lines are perpendicular to each other.

Given, three lines A, B and C.

Line A moves to the same direction as Line B

⇒  Line A║ Line B

Line B makes perfect right angle with line C

⇒ Line B ⊥ Line C

From the given statements

we can conclude

⇒ Line A ⊥ Line C

Hence,  Line C ⊥ Line A

You can visually see that both of the long sides of that triangle are equal. See how they look the same? The other side of that triangle (the distance between the Big Top Tent and the Pirate Ship) has a given length written, it says "25 m." So the x side, which is equal is also 25 m. The value of x is 25 m.
