What is x for unknown angle problems with algebra?

x = 20

Step-by-step explanation:

We see that the whole measure angle is equal to 90 degrees. According to Part-Whole-Postulate, if we add the smaller angles, we will get 90 degrees. Knowing this, we can form an equation to find the value of x.

x + 2x + (x + 10) = 90

Now you just solve this equation

x + 2x + x + 10 = 90

4x + 10 = 90

4x = 80

x = 20

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
