Question

question no. 3
answer please with explanation ​

Answer 1

Answer:

6.666667

Step-by-step explanation:

as linear pair =180°

one angle =68°

second angle =3x-20°

x=3÷20

6.666667

Answer 2

${\texttt{\huge{\green{SOLUTION :-}}}}$

GIVEN :

∠AOB = 68°

and

∠AOC = 3x - 20°

THEN,

by the property of straight line ( BOC is a straight line here) , we can say that

∠AOB + ∠AOC = 180°

68 + 3x - 20 = 180

88 + 3x = 180

3x = 180 - 88

3x = 92

x = 92/3

x = 30.7 (approx)

Which is the required value of x.
