Question

find the value of x in each of the figure given below​

Answer 1

Answer:

x=20°

Step-by-step explanation:

x+2x+30°=90°

3x+30°=90°

3x=90-30

X=60/30

X=20°

Answer 2

Answer:

we know that

sum of linear pair angle is 180

since, one angle is 90 degree

therefore, another angle is also 90 degree

x+2x+30=90

3x+30=90

3x=90-30

3x=60

x=60/3

x=20

therefore x= 20 degree

and another angle=2x+30

=2x20+30

=40+30

=70 degree
