Put a point H on (9, 2). Sketch a triangle out of the three points. Distance between (-2, 2) and (9, 2) is going to be 11. Distance between (9, 2) and (9, 5) is going to be 3. These correspond to the a and b of the Pythagorean Theorem
c^2=a^2+b^2
c=√11^2+3^2=√130
<span>Square root of 130 is 11.4</span>

The height of a trapezium of area 162 cm^2 is 6cm. if one of the base is 23 cm. find the other

Luden [163]

Answer:

31 cm

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = $\frac{1}{2}$ h (a + b)

where h is the height and a, b the bases

Here A = 162, h = 6 and a = 23 , then

$\frac{1}{2}$ × 6 (23 + b) = 162

3(23 + b) = 162 ( divide both sides by 3 )

23 + b = 54 ( subtract 23 from both sides )

b = 31

The other base is 31 cm
