Atrapezoid has an altitude of 14 cm. its parallel sides measure 5 and 8 cm, respectively. what is its area? 182 cm�� 91 cm�� 45.5 cm�� 280 cm��

The area of a trapezoid is 91cm² .

Step-by-step explanation:

Formula

As given

A trapezoid has an altitude of 14 cm. its parallel sides measure 5 and 8 cm.

Put  in the formula

Area of a trapezoid = 91 cm²

Therefore the area of a trapezoid is 91cm² .

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
