Question

Find x in each of the following.​

Answer 1

Step-by-step explanation:

1st

a triangle has 180 degree as the sum of all Angels

so ASP( angel sum property )

75 + 40 + x = 180

x = 180 -75 -40

= 180 - 115

= x = 65 degrees

2nd the same method

the square at side is 90 degree

x + 90 + 36 = 180

x = 180 - 126

x= 54 degrees

3rd the same but here x are 2 these means both have same value so it's 2x

so ASP

2x + 52 = 180

2x = 180 - 52 = 128

2x = 128

x = 128/ 2 = 64

x = 64

4th the same but here value is not there but there are x + 10 , x-10 ,x

so ASP

x + x + 10 + x - 10 = 180

so 10-10 = 0

x + x + x = 180

3x = 180

x = 180/3 = 60

x = 60

x + 10 = 60+10 = 70

x - 10 = 60 - 10 = 50

5th the same as 4th

x + 2x + 25 + 2x -5 = 180

25 - 5 = 20

5x + 20 = 180

5x = 180-20 = 160

x = 160/ 5

x = 32

2x + 25 = 2* 32 + 25

= 64 + 25 = 89

2x -5 = 2* 32 - 5

= 64 -5 = 59

so all are done hope it helps the star is multiply

plz mark me brainest thank you.
