Question

In triangle ABC , angle A is double than angle B but angle C is 5 less than angle A .find Angle B​

Answer 1

Answer:

angle B=2*65 = 130

Step-by-step explanation:

Sum of all angles of a triangle=180

Let angle A=x, angle B=2x, angle C=x-5

X+2x+x-5=180

3x-5=180

3x=180+5

3x=195

x=195/3

x=65

angle B=2*65 = 130

Answer 2

Answer:

hope it helps

Step-by-step explanation:

A=2B ,

or,B=A/2

and

C=(A-5)

we know,

A+B+C=180°

or,A+A/2+A-5=180°

or,2A+A/2=180+5

or,(5A)/2=185

or,5A=185×2

or,A=185×2/5

or,A=37×2

or,A=74°

B=74/2

or, B=37° {Ans}
