The Measures Of Two Angles Of A Triangle Are 75 And 62. Find The Measure Of The Third Angle.13c. 470b.

Answers

Answer 1

Answer: B 43

Step-by-step explanation:

Well for a triangle it has to be equal to 180 so you would add 75 and 62 to get 137 so you would add each answer to 137 and whichever one equals 180 is the answer therefor stating that the answer is B 43.

Subtract 36 from both sides
You then get 3x=-30

(-2,3) is one vertex of a square on a coordinate plane. Name three points that could be the other vertices.

Answers

Answer:

(0,7) and (-4,7)

(-2,3) is vertex

Equation is (X+2)2+3

When x = 0, y = 7 and when x = -4, y = 7

(-2,3) is one vertex of a square on a coordinate plane. (0,7) and (-4,7) could be the other vertices.

How can we perceive the cartesian coordinate plane?

The cartesian coordinate plane is an infinite 2-dimensional plane. Any 2-dimensional figure can be drawn on an infinite 2d plane.

Each point of a cartesian plane is tracked by a location.

It is the perpendicular distance of that point from the horizontal axis and vertical axis usually named the x-axis and y-axis.

The location is then written as: (a,b), where 'a' is that point's shortest distance from the y-axis and called the x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis and called the y-coordinate of that point.

(-2,3) is one vertex of a square on a coordinate plane.

The equation is [tex](X+2)^2+3[/tex]

When x = 0,

[tex](0+2)^2+3\\\\4+3[/tex]

y = 7  

when x = -4,

[tex](-4+2)^2+3\\\\4+3[/tex]

y = 7

Describe the angle relationship and solve for the x.

​

Answers

Answer:

x = 25

Step-by-step explanation:

The shown angles appear to be on a straight line

Angles on a straight line have a sum of 180°

That being said we can create an equation using this relationship

180 = x + 2 + 153

now we solve for x using basic algebra

step 1 combine like terms

153 + 2 = 155

now we have 180 = x + 155

step 2 subtract 155 from each side

180 - 155 = 25

155 - 155 cancels out

we're left with x = 25

Answers

Answer:

Table:

12, 450

Population after 12 years is 450 deer

Initial population is 200 deer.

Step-by-step explanation:

You take the x in the table and plug it in as an exponent so you will need a calculator or multiple the 1.07 by that many times so 1.07 12 times multipled by itself. and the initial is 0 years so anything to the exponent of 0 is 1 so that show i got 200 for the x=0

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:

rectangle with length of x ft and width of x minus 4 ft, right triangle inside labeled stage with height of x minus 4 ft and base of 6 ft, rectangle inside labeled closet with length of 7 ft and width of 2 ft, the rest of the rectangle is labeled floor

Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).

A = x(x − 4) + 0.5(6)(x − 4) + 2(7)
A = x(x − 4) − 0.5(6)(x − 4) − 2(7)
A = x(x − 4) − (6)(x − 4) − 2(7)
A = x(x − 4) + (6)(x − 4) + 2(7)

Answers

Answer: A=x(x-4)-0.5(6)(x-4)-2(7)
