Question

Can someone pls help me i don't understand this

Answer 1

one more find root out them ok and c= 75 and b= 16

i hope help you mark me brainlist thank you difficulty

Answer 2

Answer:

1.Pythagoras theorem =AC²=AB²+BC²

let's consider the triangle as ABC

So AB=21 and BC=72

Applying the formula to get c that's AC²

AC²=(21)²+(72)²

=441+5184

AC=√5625

AC=c=75

2.Pythagoras theorem =AC²=AB²+BC²

let's consider the triangle as ABC

so AB =12 and BC=?

Here we should find BC

so BC²=AC²-AB²

BC²=(20)²-(12)²

=400-144

BC=√256

BC=b=16

3.Pythagoras theorem =AC²=AB²+BC²

let's the consider the triangle as ABC

here we should find AB

So AB²=AC²-BC²

So AB²=(70)²-(26)²

=4900-676

AB=√4224

AB=64.99=65

AB=a=65
