In a triangle there is 180 degrees

Answer:

<u>D</u>

Step-by-step explanation:

  • The <u>Angle Sum Property of a Triangle</u> states that the internal angles of a triangle add up to 180°
  • Here, the sum is : 130 + 30 + 30 = 190°
  • Therefore, the angle measurements are not correct
  • The total angle measure of triangle should decrease by 10°
  • By making the top angle 120°, the sum becomes 180°
  • Hence, <u>D</u> is the correct option

(6(1) = -5<br> 1) Find (4) in the sequence given by<br> (6(n) = b(n − 1) +9
Sloan [31]

Answer:

f(4) = 22

Step-by-step explanation:

I think that you type wrongly.

we have f(1) = -5

and f(n) = f(n-1) + 9

Find f(4)

Then

with n= 2 we have f(2) = f(1) + 9 = - 5+ 9= 4

with n= 3 we have f(3) = f(2) + 9 = 4 + 9= 13

and finally with n= 4 we find f(4) = f(3) + 9 = 13+ 9= 22

So f(4) = 22

Hope you understand.

HELP!!!!!!!!!!!!!!!!!!!!!!!
Agata [3.3K]

Answer:

B would be (-1, -2)

C would be (-1, 1)

A would be (-4, -2)

Step-by-step explanation:

The ordered pairs are affected by the y value. The X value stays the same since you didn't move the shape any to the right or left. The y values went down three on all of the points because you moved the whole shape down three spots.

I hope this helps! Please mark as brainliest! Just ask if you need anymore help! :D Good Luck!
