There are 180 degrees total in a triangle and the tell you one angle is 90. So you solve the equation 4x+6x=90. So x=9
$489.50+x=$756.80
x=amount paz has.
756.80-489.50 = 267.3
so Paz has $267.30
It should be 100 because it has to add up to 180 and 50+30=80 so the third angle must be 100
|76| is 76 because it is 76 units away from zero.
