Question

∆ABC is a right angled at A, and AB=AC find angleB and angleC

Answer 1

Answer:

Step-by-step explanation:

AB=AC {given

Therfore,angle B =angle C{isosceles triangle theorem90

Let,angleA=angleB=X

angle A+angleB+angleC=180{angle sum property of triangle

90+X+X=1180

90+2X=1180

2X=990

X=45°

therefore ,angleA=angleB=45°

Answer 2

Answer:THE ANGLE B IS 45 DEGREES.AND ANGLE C IS ALSO 45 DEGREES.

Step-by-step explanation:TRIANGLE ABC IS RIGHT ANGLED AT A.

THE VALUE OF A=90 DEGREES

GIVEN:-AB=AC

LET THE VALUE OF B AND C BE X

A+B+C=180

90+X+X=180

2X=180-90

2X=90

X=90/2

X=45.

THEIR FORE THE VALVE OF B IS 45 DEGREES AND C IS ALSO 45 DEGREES.
