Question

triangle ABC is right angled at b, if sin(A-C )=0 then value of 2A+C=

Answer 1

Step-by-step explanation:

angle B=90

sin(A-C)=0

then

(A-C)=0

A+B+C=180

so,

A=45

B=90

C=45

A+C=90

THEN,

2(A+C)=2(90)=180

Answer 2

Answer:

No the answer is 135 bcoz its written 2A+C not 2(A+C)

Step-by-step explanation:

2A+C

2×45+45

90+45

135
