What Is The Value Of X class=

Sagot :

Answer:

x = 10

Step-by-step explanation:

All angles in a triangle must add up to 180. We know one angle is 68 and another is 90 because there is a right angle (which are always 90).

180 = 90 + 68 + (2x + 2)

180 = 158 + (2x + 2).      subtract 158 from both sides

22 = 2x + 2.     subtract 2 from both sides

20 = 2x.       divide both sides by 2

10 = x

Answer:

x = 10

Step-by-step explanation:

2x + 2 + 68 + 90 = 180

2x + 160 = 180

2x = 20

x = 10
