It would be 6 feet less than whatever the measure of the width is.
You would find the measure of angle U which is 33. Then you would add 8x+12x and get 20x then you would add 33 and 7 and get 40 so you have 20x+40=180 (because all of a triangles measures = 180) then you would minus 40 from both sides you now have 20x=140 then divide by 20 and x=7 then you would go back and do 12(7) . Then your angle = 84
When we are given a system of 3 linear equations, with 3 variables, we proceed as follows:
We consider 2 pairs or equations, for example (1, 2) and (2, 3), and eliminate one of the variables in each pair, creating a system of 2 linear equations with 2 unknowns.
Note that the third equation contains -2y which can be used to eliminate easily -6y in the second equation, and -4y in the fourth.
i) consider equations 1 and 3:
-3x-4y-3z=-7
5x-2y+5z=9
multiply the second equation by -2:
-3x-4y-3z=-7
-10x+4y-10z=-18
adding the 2 equations we have -13x-13z=-25
ii) consider equations 2 and 3. Multiply the third equation by -3:
2x-6y+2z=3
-15x+6y-15z=-27
adding the 2 equations we have -13x-13z=-24
So we got -13x-13z is -25, but also -24. this means the system is inconsistent, so it has no solution.
Answer: the system has no solutions
Answer:
oof that is hard.
Step-by-step explanation:
Answer:
x = 22.5
Step-by-step explanation:
flat angle (straight line) = 180
right angle = 90
given the picture,
x + 3x = 180-90
4x = 90
4x/4 = 90/4
x = 22.5
