From the diagram, what can you conclude about cad?

a.) it’s an isosceles triangle
b.) it’s an equilateral triangle
c.) it’s an obtuse triangle
d.) it’s an equiangular triangle

ΔCAD is isosceles triangle

Step-by-step explanation:

Given the diagram in which BC=ED, ∠C=∠D and ∠B=∠E=90°

we have to conclude about the triangle CAD

In ΔABC and ΔAED

BC=ED    (Given)

∠C=∠D    (Given)

∠B=∠E=90°    (Given)

By ASA rule, ΔABC ≅ ΔAED

By CPCT , AC=AD

The two sides of triangle CAD are equal implies

ΔCAD is isosceles triangle

Option A is correct

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
