The sum of all exterior angles add up to 360º. To find the missing 3rd exterior angle subtract the sum of the first two exterior angles from the total sum of all exterior angles.
360º - 220º = 140º
The measure of the third exterior angle is 140º.
Answer:
x=2
Step-by-step explanation:
5 ( x - 2) + 4 ( 3 + x) = 20
Distribute
5x -10 +12 +4x = 20
Combine like terms
9x +2 = 20
Subtract 2 from each side
9x+2-2 = 20-2
9x = 18
Divide each side by 9
9x/9 = 18/9
x = 2
Answer:
8 units
Step-by-step explanation:
Since the y-coordinates are the same, you are only traveling horizontally, or from left to right. Therefore, you can find the length of the segment using a number line (like the one attached!) From -3 to 0 is 3 units, and from 0 to 5 is 5 units. Since 3 + 5 is 8, the segment is 8 units long.
Answer:
x = 11.31
y = 13.86
z = 19.60
Step-by-step explanation:
8/x = x/16
x^2 = 128
x = 11.31
x^2 + 8^2 = y^2
128 + 64 = y^2 = 192
y = 13.86
x^2 + 16^2 = z^2
128 + 256 = z^2
z^2 = 384
z = 19.60
