Answer:
Step-by-step explanation:
<u>Trapezoid</u>
The trapezoid has been broken into two triangles and a rectangle. The two triangles both have the same dimensions, so both have the area ...
A = (1/2)bh = (1/2)(2 m)(5 m) = 5 m²
The rectangle has area ...
A = bh = (2 m)(5 m) = 10 m²
So, the total area of the trapezoid is ...
trapezoid area = 5 m² +10 m² +5 m²
trapezoid area = 20 m²
__
<u>Kite</u>
The kite has been broken into two triangles, so the area of each of them is ...
A = (1/2)bh
A = (1/2)(7 m)(3 m) = (21/2) m²
Then the area of the two halves of the kite will be ...
kite area = 2 × (21/2 m²)
kite area = 21 m²
__
The area of the trapezoid is <u>1 m² less than</u> the area of the kite.
You have to put the two angles in the same units, because now the first one is in radians and the second one in degress.
To pass 1.38 radians to degrees you can use the ratio 180° / π radian = 1.
So 1.38 radian * 180° / 3,1416 = 79 °.
So the angle in the Column A is 2° wider than the angle in the Column B.
