Answer:
Always
Step-by-step explanation:
The definition of a perpendicular line is that it intersects another at a 90 degree angle. Using this, by verticals, the opposite corner angle must also be 90-degrees, and since one side of a line is 180 degrees, 180-90 = 90, which ensure the rest of the angles will be 90 degrees too.
0.08.
0.8/10 is 0.08
the answer is 0.08
Answer:
200n - 162.
Step-by-step explanation:
first trem a1 = 38
common difference d = 200
nth term = a1 + (n-1(d
= 38 + 200(n-1)
= 200n - 162
The 60 represents the rate at which the train is traveling in km per hour. So, I believe the answer would be D (sorry if this is wrong, to be honest I’m just using context clues)
Answer:
<u>XZ = 25</u>
<u>X</u><u>Y = 5</u>
Step-by-step explanation:
XZ = XY + YZ
XZ = (1/5XZ) + 20
XZ - (1/5XZ )= 20
4/5 XZ = 20
5/5 XZ = (20 ÷ 4) × 5
XZ = <u>25</u>
XY = 1/5 × 25
= <u>5</u>
