5 0

Answer:−√33/7


Step-by-step explanation:

Second quadrant implies cos negative, as cos is projection from

unit circle to x axis.

sin^2+cos^2=1

cos= sqrt(1-sin^2)

sin^2 = 16/49

1-sin^2 = 33/49

sin= -sqrt(33)/7

What is the area of the trapezoid?
ratelena [41]

Answer:

29.5 inches squared

Step-by-step explanation:

The formula for the area of a trapezoid is \frac{base1 + base2 * height}{2},

so base1 = 14 inches and base2 = 30 inches

since there is a right angle, you know that the height must equal the length of the left side, so the height = 15 inches

then, 14+30+15=59 and 59/2=29.5

therefore, your answer would be 29.5 inches squared
