The area of a trapezium is 35 cm² and the distance between its parallel sides is 16 cm. if one of the parallel is of length 25 cm, find the length of the other.

No solution

Step-by-step explanation:

A = (b1 + b2)h/2

A = 35 cm²

h = 16 cm

b1 = 25 cm

b2 = ?

35 = (25 + b2)(16)/2

70 = (25 + b2)(16)

70 = 400 + 16b2

16b2 = 330

b2 = 330/16 = -20.625

The answer is a negative number. Since the base of a trapezium cannot have a negative length, there does not exist a trapezium with the given information.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
