Question

an angle A of a triangle is double of the another Angle B of the triangle if the third angle C is 105 degree find the angle A and B

Answer 1

Suppose angle B is x
so angle A = 2x
Now, x+2x+105=180
or, 3x=180-105=75
or, x=75/3=25(Value of angle B)
Hence value of angle A=25×2=50

Answer 2

Answer:

A= 50 and B=25

Step-by-step explanation:

let the angle B is x

therefore, angle A=2x

x+2x+105=180

3x=180-105=75

x=75 =25( VALUE OF ANG. B)

3

SO,value of ang. A =25×2=50.
