Answer:
The two parallel sides a and b are 17 cm and 23 cm respectively
Step-by-step explanation:
Area of a trapezium = {(a+b)/2} h
Where
h = height = 18 cm
a = parallel side 1 = x
b = parallel side 2 = x + 6
Area of a trapezium = {(a+b)/2} h
360 = {(x + x + 6) / 2} 18
360 = { (2x + 6) / 2} 18
360 = (2x + 6) 9
360 = 18x + 54
Subtract 54 from both sides
360 - 54 = 18x
306 = 18x
Divide both sides by 18
x = 306 / 18
= 17
x = 17 cm
a = parallel side 1 = x
x = 17 cm
b = parallel side 2 = x + 6
x + 6
= 17 + 6
= 23 cm
Answer: 22.5
Step-by-step explanation:
Answer:
464
Step-by-step explanation:
Find other angle:
<B = 180 - 165 - 11 = 4
Then plug in (opposite sides go together):
= 
21a: 4
21b: 7
21c: 10
22. 3 to the 4th power
The Answer Is 90
Write 45% as 45100.
45100 of 200 = 45100 × 200.
Therefore, the answer is 90. If you are using a calculator, simply enter 45÷100×200 which will give you 90 as the answer.
