The measure of Angle B is 68° what is the measure of it supplementary anglea. 22°
b. 90°
c. 112°
d.180°

Answers


"Supplementary angles" means two angles that add up to 180°.

                             (Any angle) + (its supplement)  =  180° .

                                 (Angle B) + (its supplement)  =  180° .

                                        (68°) + (its supplement)  =  180°

Subtract (68°) from each side:        Its supplement = 180° - 68°

                                                                              =  112° .

Hi

A = 180º-B
A = 180º-68º
A = 112º

Answer: c) 112º

One
Two
Infinitely many

can you maybe answer quickly. I need help asap

Answers

Answer:

Option A is correct.

The Solutions can be found for the equation 4x − 8 − 4x = 9 is, Zero

Step-by-step explanation:

Given the equation:

4x-8-4x= 9

Like terms are those terms which have same variable to the same power.

Combine like terms;

-8 = 9

⇒The equation does not have any solution

Therefore, the Solutions can be found for the equation 4x − 8 − 4x = 9 is, Zero
when solving for x you get 4x-4x which equals 0 meaning there are zero answers

Jason watched a caterpillar move 10 feet in 2 minutes. Jason says that the caterpillar's unit rate is 0.2 feet per minute. Is Jason correct?

Answers

No. To get the right answer you would need to get it to how many feet it moves per minute. So you would need to divide them both by 2.
2 divided by 2 is 1
10 divided by 2 is 5
So the caterpillar is moving at 5 feet per minute.
I hope that helps! :)

The answer is 25 centimeters.

An object moves backwards from where it starts 100 meters in 20 seconds. What is the velocity of the object? Select one:

5 m/s2


-5 m/s


5 m/s


- 5 m/s2

Answers

5m/s

The formula to find the velocity is distance/time.

So 100/20 is 5m/s.
It’s not 5m/s2 because this is the unit for acceleration.
And it’s not negative because it is not possible for the velocity to be negative.

Hope this helped. Mark me Brainliest please:)
