To answer this question, you should draw it out- see the attached picture for the example. All the side lengths are labeled. You can then use the area of a trapezoid formula to find the total area.
A=1/2 (b1 + b2)h
You can see the substitution for each value in the work shown in the picture.
Answer:
46
Step-by-step explanation:
Taking the absolut value means taking an expression's distance from zero (like on a number line).
-46 is 46 units away from zero, therefore your answer is 46.
Answer:
cosA = - 
Step-by-step explanation:
Using the double angle identity
cos2A = 2cos²A - 1 , then
cosA = 2cos²(
) - 1 , that is
cosA = 2 × (
)² - 1
= 2 ×
- 1
=
- 
= -
