Question

if the points A,O and B are collinear,find the value of x in each of the following​

Answer 1

Step-by-step explanation:

$\large \bold{question : (find \: x)}$

$\bold{ \: Solution} :$

$\bold \colorbox{lime}{given} :$

25°, 90°, 30° x°

$\huge \bold\color{blue}{we \: know \: that : }$

The sum of a semicircular circle : 180°

Therefore,

$\bold{25 + 90 + 30 + x = 180}$

$\bold{145 + x = 180}$

$\bold{x = 180 - 145}$

$\bold{x = 35}$

Therefore,

The value of x = 35°
