It is

The equation for area of a trapezoid is

Substituting our values in

We can then simplify the expression

Answer:
20 degrees
Step-by-step explanation:
every triangle had 3 angles that all add up to 180
the problem gives you two angles which are 120+40 which is 160
180-160 is 20 degrees which is whi it is the answer
The equation cannot be solved, but it can be simplified.
You can't add variables with different exponents. For example, you can't add
with
because they have different exponents
