Ummmmm well first you.. UHG how do i explain dis
let me get my bearings straight and i will come back to u :)
Answer:
The Pythagorean Theorem leads to a simple proof of the Pythagorean Identity using only the basic definitions of trig functions. The Pythagorean Theorem on a right triangle with legs a,b and hypotenuse c gives us: a2+b2=c2. Dividing through by c2 gives: (ac)2+(bc)2=1.
Ok so a) is integers
And b) is 21
Explaining for B
From 1-3 he added 2
From 3-6 he added 3
From 6-10 he added 4
From 10-15 he added 5
So we r gonna continue the sequence by adding 6
15-21 we added 6
Just add the same sides and angles
The answer is 9. hope I helped
