we know that
In the <u>isosceles trapezoid</u> of the figure, the angles on either side of the bases are the same size/measure (congruent), and adjacent angles (next to each other) along the sides are supplementary.
so
m∠A=m∠B=3x
m∠D=m∠C=9x
m∠A+m∠D=
Substitute
therefore
<u>the answer is</u>
the value of x is equal to
<span>[(7 x 6) + 15]2 + 8
(42+15)2+8
57*2+8
114+8
122
HOPE THIS HELPS!!</span>
What? I don’t understand lol
Y=mx+b
ok, so notice that b is constant, doesn't change, when x=0, then y=b
that is the starting value
it is stated that he has 41 at the begining so
y=mx+41
alright
so we are also given
when x=5, y=66
so find m
66=5m+41
miinus 41 from both sides
25=5m
divide both sides by 5
5=m
the equation is
y=5x+41
