# Children playground

The playground has a trapezoid shape, and the parallel sides have a length of 36 m and 21 m. The remaining two sides are 14 m long and 16 m long. Find the size of the inner trapezoid angles.

A =  53.5764 °
B =  66.8676 °
C =  113.1324 °
D =  126.4236 °

### Step-by-step explanation:

$C=180-B=180-66.8676=113.1324\text{°}=113\mathrm{°}{7}^{\mathrm{\prime }}57\mathrm{"}$
$D=180-A=180-53.5764=126.4236\text{°}=126\mathrm{°}2{5}^{\mathrm{\prime }}25\mathrm{"}$
