Answer:

619.5cm2

Step-by-step explanation:

Based on what you defined as the parallel sides been 26cm and 33cm and the height been 21cm.

Hence the are of trapezium is half sum of the parallel sides × height.

Expressed mathematically we have:

1/2( 26 +33) × 21 = 1/2 ( 59) × 21 = (59×21)/2= 619.5cm2

-7.66666, \sqrt(50,) -(157)/(20), -7.64 list these from least to greatest.
blagie [28]

Answer:

From least to greatest, the correct order is: -\frac{157}{20}; -7.666....; -7.64; and \sqrt{50}.

Step-by-step explanation:

Since \sqrt{50} is the only positive number, that means that it will be the greatest number on the list. -\frac{157}{20} is equivalent to -7.85, which makes it the smallest number. So you can conclude that the correct order is -\frac{157}{20}; -7.666...; -7.64; and \sqrt{50}.

the altitude of the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 14 and 8. what is the length
lisov135 [29]

Answer:

B. 4\sqrt{7}

Step-by-step explanation:

The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.

This can be represented as:

h = \sqrt{(xy)}

Where,

h = the length of the altitude,

x and y are the lengths of the 2 segments formed.

Therefore, the length of the altitude = h = \sqrt{(14*8)}

h = \sqrt{112}

h = \sqrt{16}*\sqrt{7}

h = 4\sqrt{7}
