Find the value of x ​

Mathematics
1 answer:
givi [52]3 years ago
3 0

Answer:

110°

Step-by-step explanation:

In triangle AOB

OA = OB (radii of same circle)

m\angle OAB = m\angle OBA =20\degree

m\angle AOB = 180\degree - (20\degree +20\degree)

m\angle AOB = 180\degree - 40\degree

m\angle AOB = 140\degree

m\widehat {ACB} =m\angle AOB = 140\degree

(measure of minor arc is equal to corresponding central angle)

x\degree = \frac{1}{2} (360\degree - 140\degree)

(inscribed angle theorem)

x\degree = \frac{1}{2} \times 220\degree

\huge\purple {x = 110}

What set of transformations is performed on triangle ABC to form triangle A'B'C'?
jonny [76]
In order to answer this question, you would need to provide a coordinate, but since this question lacks that, I will explain transformations. Transformations are like moving an object throughout a room, in this case, the room is a graph. The Y coordinate
(X, Y) is moving things higher or lower, or in this case up and down the graph. The X coordinate (X, Y) is moving things forward and backwards, or left and right on the graph. So in order to find your Transformation, you need to take what was your item's original position, it's X and Y locations, and subtract from that your new location.

Here's an example, if I had a triangle with sides and corners labeled A, B, and C or for short, triangle ABC, if A is located at (1 , 0), B is located at (3 , 3) , and C is located at ( 5 , 0) what is its new transformation if it is moved up 3 and right 1?

You would then add 1 to each angle's X coordinate and add 3 to each angle's Y coordinate. Resulting in this:
A (2 , 3)

B (4 , 6)

C (6 , 3)

The equation below expresses the approximate
natka813 [3]

Answer:

The ball will be the 7 ft high at 2 different times.

Step-by-step explanation:

The height in meters of the ball is given by the following equation:

h(t) = -16t^2 + 25t

7 feet high

The height, by the equation, is given in meters, so we have to work in meters. Since each feet has 0,3048 meters, 7 feet have have 2.1336 meters. So, we have to solve the following equation

2,1336 = -16t^2 + 25t

16t^2 - 25t + 2,1336 = 0

At how many different times will the ball be 7 ft. High?

We have to find the number of solutions for the equation above.

It is given according to the value of \Delta = b^2 - 4ac. If it is positive, there are two solutions, zero one solution and negative no solutions.

In this equation a = 16, b = -25, c = 2.1336. So

\Delta = b^2 - 4ac = (-25)^2 - 4*16*2.1336 = 488

Since the coefficient is positive, the ball will be the 7 ft high at 2 different times.

Ganezh [65]

Answer:

55 mph

Step-by-step explanation:

First hour: 40 mph

Second, Third, Fourth hours:

180 miles / 3 hours = 60 mph

Average: 40 (hour 1) + 60 (hour 2) + 60 (hour 3) + 60 (hour 4) = 220 / 4 hours = 55 mph average

I hope this helps!
