answer the question step by step pls ​

Answer 1

Answer:

1)8²+15²=17²

64+225=289

289=289

LHS=RHS

Hence,

8,15and17 are a Pythagorean Triplet

2)In Triangles BCA and BTA,

BC=BT (Given)

AC=AT (Given)

AB=AB (Common)

By SSS congruency Criterion,

Triangle BCA is congruent to Triangle BTA

3)x=60° (Vertically opposite angles)

30°+x+y=180° (Angle Sum Property of Triangle)

30°+60°+y=180°

90°+y=180°

y=90°
