AB and CD are straight lines. Find /n.
(help me pls)
​

130°

Step-by-step explanation:

Since AB and CD are straight lines, we can use vertical angles theorem which tells us that angles that are on opposite sides of an intersection are congruent (equal in value).

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
