Pythagorean Theorem:
a^2 + b^2 = c^2
Since you have the hypotenuse, you can change the equation to find the missing side.
a^2 - c^2 = - b^2
Insert your numbers:
9^2 - 10^2 = -b^2
What do you get?
Its a trapezium. and the perpendicular lines will be ut perpendicular to st and st perpendicular to sv
Do you have a photo of it?
Sequence: 1, 3, 6, 10, 15, …
If sequence is arithmetic,
If sequence is geometric,
<u>Check </u>for arithmetic:
Hence, the sequence is not arithmetic
<u>Check </u>for geometric:
Hence, the sequence is not geometric
