Guys please help me it’s geometry and I really don’t know how to do these
1 answer:
m is the midpoint of AB
A——4x-1———M——3x+3—-B
Find the values of
X=
AM=
MB=
AB=
Since this is like a line, we know it totals up to 180°.
A + (4x-1) + M + (3x+3) + B = 180
Simplify the two values with "x" in them
(7x+2) + A + M + B = 180
First, let's find x.
7x = 178-A-M-B
x =
Next, let's find AM.
A + M + B = 178-7x
A+M = 178-7x-B
multiply them together and get the answer then do the same for everything else.
sorry i cant help with everything.

Answer:
EF = 22 , AB = 1
Step-by-step explanation:
the midsegment of a trapezoid is equal to half the sum of the parallel bases
EF = (AB + DC ) ← substitute values
x + 6 = (2x - 9 + x + 5) ← multiply both sides by 2 to clear the fraction
2x + 12 = 3x - 4 ( subtract 3x from both sides )
- x + 12 = - 4 ( subtract 12 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
Then
EF = x + 6 = 16 + 6 = 22
Similarly
EF = (AB + DC ) , that is
x + 3 = (4x - 3 + 2x + 5 ) ← multiply both sides by 2 to clear the fraction
2x + 6 = 6x + 2 ( subtract 6x from both sides )
- 4x + 6 = 2 ( subtract 6 from both sides )
- 4x = - 4 ( divide both sides by - 4 )
x = 1
Then
AB = 4x - 3 = 4(1) - 3 = 4 - 3 = 1
Divide the seats filled by the total amount of seats of the classroom.
Multiply this result by 100 to find the percentage.
The classroom has 70% of the seats filled.
