Question

In the figure given below SABC, AD 1 BC, find the value of x.
​

Answer 1

Answer:

X=30°

Step-by-step explanation:

90°+3x=180°

3x=90°

X=30°

Answer 2

Answer:

x = 30

Step-by-step explanation:

We know that

All angles add up to 180°

So,

90° + 2x + x = 180°

90° + 3x = 180°

Transposing 90° from LHS to RHS to get -90°

3x = 180° - 90°

3x = 90°

Transposing 3* from LHS to RHS to get /3

x = 90°/3

x = 30
