OK. I used my calculator to evaluate sec(85 degrees).
My calculator doesn't have a "sec" button on it.
But I remembered that
sec of an angle = 1 / (cosine of the same angle) .
So I used my calculator to find cos(85), and then I hit the
" 1/x " key, and got 11.474, which I knew to be sec(85).
Answer:
Area of the Trapezoid is= 
Step-by-step explanation:
The given figure is in the shape of a trapezoid:
Area of a trapezoid= (1/2)*(Sum of parallel opposite sides)* (Distance between the parallel sides)
The parallel sides are: 6 cm and 3 cm
Distance between parallel sides= 3 cm
Area:

Area of the Trapezoid is= 
Answer:
3u-15
Step-by-step explanation:
