complementary
two coplanar angles with a common side and vertex
adjacent angles
is -5 a solution
-24-5x=-8+3(x+8)
yes
answer: 1=1
two angles whose sum is 180 degree
supplementary
two angles who sides are opposite rays
vertical angles
solve the equation
2n-4(-6n+7)=8n+26
n=3
a right angle is what
complementary
a pair of adjacent angles with opposite rays and forms a straight angle
linear pair
solve the equation
-6(x-5)=3(-6-x)
x=-4
a line is what
supplementary
a line is what
straight angle
solve the equation
-6(2+8m)+5(4-4m)=76
m=-1
what are two angles whose sides are opposite rays
vertical angle
obtuce
is -5 a solution
6(p-4)-8p=6(1+2p)-8p
yes
answer: -14=-14
