we are given

Angles A and B are supplementary

we know that when angles are supplementary

then sum of all these angles must be 180

we have

first angle is A

second angle is B

we get

A+B=180

now, we have

A=80

so, we can plug it and solve for B

80+B=180

Subtract both sides by 80

80+B-80=180-80

B=100.................Answer

<u>Answer:</u>

B = 100°

<u>Step-by-step explanation:</u>

Two angles are said to be supplementary if the sum of both the angles is equal to 180 degrees.

Supplementary angles do not necessarily have to be next to each other as long as they add up to 180 degrees.

In the given problem, we know that angle A = 80°. If A and are supplementary angles, then:

A+B= 180°

80°+B=180°

B= 180°-80°

B=100°

Therefore, angle B = 100°.

Answer:

G, 113.04

Step-by-step explanation:

To find the area of the head of the nail you need to use the*

> A= π*r^2* A equals area, π equals pi(3.14) and then you square your raidius, which is 6 in your case.

π*r^2

plug in your six as the *r

π*6*^2

solve 6^2=36 and multiply that by your π which is 3.14

3.14*36

=113.04

Hope that helped!! :)

For what values of t on the interval [0, 21 ]is the instantaneous velocity positive​ (the projectile moves​ upward)?
OLEGan [10]

Answer:

0 <=t<=21

Step-by-step explanation:

Projectile is Moving upwards on an interval of (0 to 21), if we plot Velocity vs Time and denote positive y-axis above 0 and negative y-axis below  0(for velocity), then from 0 to 21 t projectile is moving upwards and has positive velocity, when the projectile reaches the top of it's motion and returns back down to ground it's velocity is negative and is plotted below the y =0 (note that is for t > 21).

hence for the interval 0 <=t <=21 the instantaneous velocity is positive (Note, instantaneous velocity is also the derivative of the velocity or the slope ).
