Question

in a right triangle ABQ if AQ=8 cm then AB? angle A=45degree B=90 degree lesson pythagoras theorem​

Answer 1

Answer:

AB=4 root2

Step-by-step explanation:

A=45degree B=90 degree-Given

So Q=45°

By 45-45-90° triangle theorem

Sides opposite to 45 degree angles=1/root 2 *hypotenuse

AB=BQ=1/root 2 *AQ

AB=1/root 2*8

AB=8/root 2

AB=root 64/root 2

AB=root(64/2)

AB=root 32

AB=root 16*2

AB=4 root2

$ab = 4 \sqrt{2 \: } cm$
