Answer:

4/45

Step-by-step explanation:

First find all the pairs that make 9 that are two digit:

1+8

2+7

3+6

4+5

5+4

3+6

2+7

1+8

That's 8 pairs, and as there are 90 two digit numbers, 8/90 is the answer. but if you want to simplify, the answer is 4/45

Answer:

<h2><u>x = 8.2</u></h2>

Step-by-step explanation:

A^2+B^2=C^2 is the pythagorean theorem to find a missing siede of a triangle.

First triangle on the right:

5^2+B^2=10^2

25+B^2=100

B^2=75

B=8.66025404

B=8.7

Second triangle of left:

3^2+B^2=8.7^2

9+B^2=75.69

B^2=66.69

B= 8.16639455

B=8.2

x=8.2
