Question

From the following figure find :
x
ABC
ACD​

Answer 1

Answer:

X=26

Angle ABC=256°

Angle ACD=256°

Explanation:

Sum of all sides =360°

here,

48+x+4x+3x+4x=360°

48+12x=360°

12x=360°-48

12x=312°

x=26°

Then the side angles are

Angle A=48°+x=48°+26°=74°

Angle B=4x=4×26°=104°

Angle D=104°

Angle C=360°-74°+104°+104°=78°

we know Angle C=3x=78°

then we find

Angle ABC=256°

Angle ACD=256°
