Atractor-trailer travels 205.296 miles in 3.12 hours. what is the speed at which the tractor-trailer is traveling? 62.05 miles per hour

65.8 miles per hour

Step-by-step explanation:

Distance traveled by a tractor-trailer=205.296 miles

Time taken to travel the distance=3.12 hours

We know that speed=

Dividing 205596 by 3120, we get 65.8

Thus Speed= 65.8 miles per hour

Therefore, the tractor-trailer is traveling with a speed of 65.8 miles per hour.

(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

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
