Answer:
Exact Form:
1/25
Decimal Form:
0.04
Step-by-step explanation:
Make sure you multiply. That should get you to your answer.
Hope this helps.
Every triangle angles add up to 180.
So because one angle is 90 degrees you would subtract it from 180 to get 90 and then divide it by two which is 45 degrees.
Hope this helps, have a nice day! :)

Answer:
∠RST = 120°
Step-by-step explanation:
We assume the positions of the lines and angles will match the attached figure. The angle addition theorem gives a relation that can be solved for x, then for the value of angle RST.
∠RSU +∠UST = ∠RST
__
78° + (3x -12)° = (6x +12)° . . . . . substitute given values into the above
54 = 3x . . . . . . . . . . . . . . . . divide by °, subtract 3x+12
108 = 6x . . . . . . . . . . . multiply by 2
120° = (6x +12)° = ∠RST . . . . add 12, show units
The measure of angle RST is 120 degrees.

<em>Additional comment</em>
Note that we don't actually need to know the value of x (18) in this problem. We only need to know the value of 6x.
The answer is just -x/4 because you can divide a variable
