Okay, what do we know?
1*6=6, right?
Well, then 9*6=? (you should know your math facts by now)
2(4x - 9) =
2 * 4x - 2 * 9 =
8x - 18
Hope this helps!!

Answer:
Isosceles trapezoid
Step-by-step explanation:
-An isosceles trapezoid is also sometimes called a convex quadrilateral.
-It properties include:
- A line of symmetry can often bisects a pair of opposite sides.
- It has to obtuse alternating with each other after which a pair of acute angles alternate with each other i.e 80°, 80°,100°,100°
- It has a trapezoidal shape which by definition has a two pair of parallel sides.
- The angles on it's base or ceiling are equal hence the name Isosceles Trapezoid.
The answer is 75 degrees. These are supplementary angles so
180-105 = 75
