Question

If ∠B=∠Y=90°, AB=12 cm and BC=5 cm, find XZ.

Answer 1

Answer:

triangle ABC = triangle XYZ

therefore, AC=XZ

according to pythagorus theorem

ACxAC=12x12+5x5=144+25=169

AC=13

AC=XZ=13cm

Answer 2

FIRST,

•LB=LY=90°

•LB=90°

•LY=90°

•AB×BC=12×5

=60CM²

$\binom{ 60}{2}$

•X = 30CM²

$\binom{60}{2}$

•Y=30CM³
