Solve for x. 6 -10 7 -9

Mathematics
1 answer:
olasank [31]3 years ago
3 0

Answer:

x=7

Step-by-step explanation:

The triangle is right angled meaning that one of the angles is 90⁰.

90+30+(9x-3)=180 (Angle sum property of a triangle)

120+9x-3=180

9x-3=180-120

9x-3=60

9x=60+3

x=63/9

<em><u>x=7</u></em>

The angle will be (9×7)-3=<u>60⁰</u>

INSERT TWO RATIONAL NUMBERS BETWEEN 2 AND 3. How to find them?
Kay [80]
There are an infinite number of them.
Here are a few:

2.1
2.2
2.3
2.3000000001
2.30000000000000006
2.5
2.00009
.
.
etc.

How to find them:

You probably never heard this before, but I'll bet
you'll remember it from now on:

<em>ANY number that you can write down on paper completely, </em><em>using digits
and a decimal point if you need it but no symbols, is a rational number.</em>

If you can write it down completely without any 'comments', then it's rational.
