Question

The second angle of a triangle is the same size as the first angle. The third
angle is 12 degrees larger than the first angle. How large are the angles?​

Answer 1

Answer:

let angles be a.b.c

Step-by-step explanation:

given a=b

c=12+a

as we know a+b+c=180

a+a+12+a=180

3a=168

a=56

largest angle =68

cheers

Answer 2

Answer:

pls mark as brainest

Step-by-step explanation:

if the 1 ang. is equal to 2 ang. , then

let angle 1 and 2 be x

if the 3 ang. is 12 degreed larger than the 1 ang. ,then

let the 2 ang. be x+12

now,

x+x+(x+12)= 180 (sum of all angles of a triangle is 180 degree)

3x+12=180

3x=180-12

x=168/3

x=56
