Answer:
A) 75
Step-by-step explanation:
All 3 angles of any triangle add up to 180° so we can subtract all known angles from 180° to get the missing angle.
40°+65°=105°
180°-105°
75°
4 i think
If you fold this figure some times it should get it evenly
$153
6x^2+9x-6
(3x+6)(2x-1)=6x^2+12x-3x-6=6x^2+9x-6
