Answer:

Try 41 degrees

Step-by-step explanation:

Because the ball bounced on the floor so that means it would have created a 90 degree area, then is bounced 49, so 49+x=90

x=41 degrees

ASAP HELLP PLS, WILL GET BRAINLIEST FOR FIRST CORRECT ANSWER!!!
lorasvet [3.4K]

Answer:

A regular polygon all the angles, as well as all the sides, are equal.

Diego's claim is the quadrilateral with four congruent sides is always a regular polygon. He is only mentioning that the sides are equals.

He has not mentioned anything about the angles, the angles may or may not be equals.

In the case, if all the angles are equal too, then the claimed quadrilateral will be a regular polygon as shown in figure(a).

So, for this case, Diego's claim is correct while  Mai's claim is also wrong.

While if all the angles are not equal, then the claimed quadrilateral will not be a regular polygon as shown in figure(b).

In this case, Diego's claim is wrong while Mai's claim is correct.

So, overall, considering both the case together, none of them have the correct claim.

So, both are wrong.

4k-36 = 9k-44 what is k
Effectus [21]

4k-36 = 9k-44

add 36 to both sides:

4k =9k-8

subtract 9k from each side

-5k=-8

k = -8 / -5 = 8/5

If g:<br>x = 2x-3 4 find 9^-1 (-3)​
vfiekz [6]

The inverse function of g(x) will be g⁻¹(x) = (4x + 3) / 2. Then the value of the inverse function, at x = -3, will be 4.5.

<h3>What is inverse of a function?</h3>

Let the function will be

f: X → Y

Then the inverse function will be

f⁻¹: Y → X

The function is given below.

g(x) = (2x – 3) / 4

Then the inverse function of g(x) will be

g⁻¹(x) = (4x + 3) / 2

Then the value of the inverse function, at x = -3, will be

g⁻¹(-3) = [4(-3) + 3] / 2

g⁻¹(-3) = -4.5
