Proof: In triangle ABC
angle A= 90
angle B = angle C ( AB=AC)
lets take angle B= angle C= x
angle B + angle A + angle C = 180 ( angle sum ppty)
ANGLE A + 2X = 180
90 + 2X= 180
2X= 180-90
X= 90/2
X=45
THEREFORE ANGLE B= ANGLE C= 45

GIVEN: ABC is a right angled triangle ; LA=90 ; AB=AC
TO FIND: LB and LC
SOLUTION: since AB=AC,
LB=LC ----(1)
LB+LC+LA = 180
LB+LB=180-LA ( from 1 )
2LB=180-90
LB=90/2
LB=45
ALSO, LC =45
THEREFORE LB=45 & LC =45.

Given-
IN TRIANGLE ABC,
ANGLE A = 90 DEGREES
AB=AC

TO FIND = ANGLE B and ANGLE C

PROOF-
AB=AC (given)
So, ANGLE B = ANGLE C
ANGLE A + ANGLE B + ANGLE C = 180 degrees
90 degrees + ANGLE B +ANGLE B = 180
2 angle B = 180-90 = 90 degrees
ANGLE B = 90/2 = 45 degrees
Thus,
ANGLE B = ANGLE C = 45 degrees

angle C and angle B are equal.
therefore angle a+b+c=180
90+2y=180 (a=b)
2y+180
y=180/2
y=90
a=b=90

Given: ABC is a right angle triangle.
AC=AB
To find: SOLUTION:
AB = AC. Therefore, = 90 + x + x = 180
90+2x=180
2x= 180-90=90
x= 90/2= 45 degrees
Therefore,

Given - ABC is a right angled triangle
angle A = 90
AB = CA
To find - angle B and C
Proof : AB = AC ( given )
Angle A = 90
Angle A + Angle B + Angle C = 180
90 + B + C =180
90 + 2x = 180
2x = 180 - 90
2x = 90
x = 90/2
= 45
therefore B and C are 45 degrees

given: ABC is a right angled triangle ;A = 90 ,
AB=AC
to find - angle B and C
proof ab=ac given
angle A = 90
angle b=c
angle A + angle B+ angle C =180(angle sum property)
Angle B =90/2=45
b=c c=45 degrees

given - in triangle ABC ( right angle triangle)A = 90
AC= BC
AB = AC
to find = angle B and angle C
SOL-
AB = AC
THEREFORE ANGLE B = ANGLE C
angle A = 90 DEGREEE
ANGLE B = C
THEREFORE = angle A + angle B + angle c = 180 DEGREEE ( ANGLE SUM PROPERTY )
ANGLE B = 180-90 = 90
angle B = 90/2 = 45
therefore angle B = angle C = 45 dergees .

GIVEN:
ABC is a right angled triangle
angle A = 90 degree
AB=AC

TO FIND
Angle B and Angle C

SOLUTION
As AB=AC, Angle B=Angle C
Using Angle sum property,
Angle A + angle B + Angle C=180
90 +angle B + angle B=180
90+ 2 angle B=180
2 Angle B= 90
Angle B=90/2
=45
Therefore angle B=45
angle C=B=45

Given - ABC is a right triangle
angle A = 90
AC = AB
To find - Angle B and Angle C
Solution - Since AB = AC,
Angle B = Angle C
Therefore,
Angle A + Angle B + Angle C = 180
90 + Angle B + Angle B = 180
2.Angle B = 180 - 90 = 90
Angle B = 90/2 = 45
Therefore
Angle B = Angle C = 45 degrees

given: ABC is a right angled triangle
A=90 degree
AC=AB
to prove: find B and angle C
proof: In triangleABC,
since AB=AC
angle B is also equal to angle C
so, A+B+C=180
as given a is 90.. 90+B+C=180
B=180-90
C is also 90 as angleB=angleC
therefore

vinandrin — 2020-10-04 06:12:37 UTC

Given - Triangle ABC is right angled.
AB=AC
A=90 degrees
To Find - angle b and angle c
Proof
since AB=AC, angle B = angle C
angle A + angle B + angle C = 180
angle a + 2 angle b = 180
90 + 2 angle b = 180
2 angle b = 180-90 =90
angle b = 90/2 = 45
hence angle b = c = 45 degree
