The exterior angle is = to the 2 interior angles.
83 = (9x + 4) + (4x + 1) Remove the brackets
83 = 9x + 4 + 4x + 1 Group the like terms
83 = 9x + 4x + 4 + 1 Add the like terms.
83 = 13x + 5 Subtract 5 from both sides.
78 = 13x Divide by 13
78 / 13 = x
x = 6
So They want the angles
9x + 4 = 9*6 + 4 = 58
4x + 1 = 4*6 + 1 = 25
When you add these two together you should get 83. Do you?
Answer:
1.
Collinear points mean they are on the same line. That leaves us with answer d. F, E, G
2.
In this case, the intersection of the 2 planes is a line. 2 points both planes contain are B and C, so the intersection can be named as answer b: Line BC
3.
2 points define a line, so therefore the answer to the question is answer b. 1
Hoped this helped. If it did, could you please consider giving me a brainliest? :)
To write the slope form quation
First; find the slope of
|x| - 5 < -13
|x| < -13 + 5
|x| < -8
No solution.
