Question

calculate the value of x
​

Answer 1

Step-by-step explanation:

Have Given :-

$\scriptsize \angle{BAC} = 65°, ∠CAB = x + 20°, ∠DAE = 3x - 5°$

$\scriptsize{∠BAC} + ∠ CAB + ∠DAE = 180° \: (liner \: pair)$

$65°+x+20°+3x - 5° = 180°$

$65°+20° - 5° + 3x + x= 180°$

$80° + 4x = 180°$

$4x = 180° - 80°$

$4x = 110°$

$x = \frac{110°}{4}$

$x = 25°$
