If m angle3 = 29°, what is m angle4?

Answers

Answer 1

Angle 4 is 151° because 180-29

Answer 2

Answer:

Angle 4 is 151

Step-by-step explanation:

angle 3 and 4 form a straight line and since it is a straight line it equals 180 and since you know that angle 3 is 29 you subtract 180 - 29 = 151. And when you add that back up 29 + 151 = 180. So this is correct

Hope this helps :D

explain how you find the Area of a Circle

Answers

Answer:

A=πr2

Step-by-step explanation:

That is the formula to solve areal for a circle.

The Area of a circle is ( = π ² )

Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula ( = π ² ) , (Pi r-squared) where is the radius of the circle. The unit of area is the square unit, such as m2, cm2, etc.

is the region covered or enclosed within its boundary. It is measured in square units. Any geometrical shape has its own area. This area is the region that occupies the shape in a two-dimensional plane. So the area covered by one complete cycle of the radius of the circle on a two-dimensional plane is the area of that circle.

As we know, the is equal to of its radius, i.e. π . To find the area of circle we have to know the of the circle.
For example, if the radius of circle is 7cm, then its area will be:
Area of circle with 7 cm radius = πr2 = π(7)2 = 22/7 x 7 x 7 = 22 x 7 = 154 sq.cm.

Answer:

Step-by-step explanation:

Rotating CCW 90 ° will cause this change in coordinates

Answer: Is would be A

Step-by-step explanation: Because since it is 90 degrees counterclockwise you would do the 270 formula since it is counterclockwise and the formula for 270 degrees is basically swapped the x and the y and add a negative to the original y and if it's already a negative it becomes a pthe polygon, so the answer is A (0, 0), B(-2, 5), C(5, 5), D(3, 0) the first one

-7

Step-by-step explanation:

First you plug all the terms in. Once you've done that, you realize what tou have is -5-4 -1+-3

First you solve the first part (-5-4) and get -9.

Then you solve the second half (1+-3) and get -2

You then have the equation -9--2

But because you're subtracting a negative, it turns into a positive.

So now our equation is -9+2

And you get -7.

The answer is -7………….

What is the proportional equation for the graph below:

Answers

Answer:

Step-by-step explanation:

y=4/2x

m = slope = (15-0)/(6-0) = 15/6 = 5/2

This graph is linear, so it can represented by the function y = mx + b, where m = 5/2 and b, the y-intercept, is 0.

So the equation for the graph is y = (5/2)x.

4(-5) + 5 = -20 + 5 = -15

Therefore, the values of the expression for y = 5, 0, and -5 are 30, 5, and -15, respectively.
