X=6.62
x+1.91=8.53
you have to subtract 1.91 from both sides of the equation to get x alone on one side of the equation. Once you do that you end up with x on one side and 6.62 on the other side, giving you the answer to x.
It means the same:
2x - 6 + 9 = 3x + 3 + x
2x +3 = 4x + 3
2x - 4x = 3 - 3
-2x = 0
x = 0/(-2) = 0
Answer:
x = 0
Answer:
74 degrees
Step-by-step explanation:
hey there,
so we know that the angles in a triangle always add up to 180 degrees
because this is an isoceles triange the 2 base angles will always be the same number of degrees.
this means that our situation can be modeled with a simple expression:
2x+32=180
which simplifies to
2x=148
x=74
Answer:
√2/2
Step-by-step explanation:
Answer:
d
Step-by-step explanation:
in order for it to be a triangle the angles have to add up to equal 180
5+75+100=180 so its not a
10+80+90=180 so its not b
20+60+100=180 so its not c
45+45+45=135 so its d because the angles dont add up to 180
50+50+80=180 so its not e
