Question

find the value of x​

Answer 1

Answer:

90°

Step-by-step explanation:

AD divides ∠BAC in the ratio 1:3

So,   let ∠BAD=y and ∠DAC=3y

now   y+3y+108=180

                   4y=72

   y=18°Now since    AD=BD

therefore,    ∠BAD=∠ABD=y=18°

∠ADC=2y=36° therefore in ΔADC

                               x+54+36=180

                                               x=90°

Answer 2

Answer:

angle BAC + angle EAC =180° {it is supplementary angle}

A.T.Q

180°-108°=72°

therefore,

Bac=72°

1:3=1x × 3x

1x × 3x = 72°

3x^2 =72°

x^2=72/3

x=4.89

therefore.

BAD=12.89

ADC= 77.11

therfore

X= 76°
