What is x if the other sides of the triangle are 16 and 4

A triangle has three sides that add up to 180 degrees. Let’s set up an equation to model this question.

16+4+x=180

20+x=180

Subtract 20 to both sides.

x=160.

You use that Pythagorean Theory which is A^2+B^2=C^2. 16^2 is 256 and 4^2 is 16. Then you add those together and you should have 272 and you square root that and your answer is 6

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
