Question

The angles of a quadrilateral are x,2x,(x-10),(x+25) degrees. Find the measure of the angle x

Answer 1

Answer:

x=69

Step-by-step explanation:

total sum of angle of quadrilateral will be 360

so

x+2x+x-10+x+25=360

5x+15=360

5x=345

x=69

additionally 2x=138

x-10=59

x+25=69+25=94

Answer 2

Step-by-step explanation:

sum of the angles in a quadrilateral = 360

x + (x - 10 ) + (x + 30 ) + 2x = 360

x+x+x+ 2x -10 +30 = 360

5x + 20 = 360

5x = 360 - 20

5x = 340

x = 340/5

x = 68

first angle = x = 68°

second angle = x - 10 = 68 - 10 = 58°

third angle = x + 30 = 68 +30 = 98°

fourth angle = 2x = 2 x 68 = 136°

i hope this useful to you.
