X=-1/9 I used a calculator
We know that tanθ = sinθ/cosθ
For a number to be undefined, the denominator must equal to 0. At π/2, the cosθ value is 0 and sinθ is 1. Hence, tan(π/2) is undefined.
Hope I helped :)
Area of entire trapezoid = <span>((sum of the bases) ÷ 2) • height
Trapezoid Area = (51 / 2) * 26
</span><span>Trapezoid Area = 663
UN-shaded triangle area = .5 * base * height
</span><span>UN-shaded triangle area = .5 * 23 * 26
</span><span>UN-shaded triangle area = 299
SHADED Trapezoid Area = 663 -299
</span><span>SHADED Trapezoid Area = 364
