Answer:

x = 82.5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + x - 45 + 60 = 180, that is

2x + 15 = 180 ( subtract 15 from both sides )

2x = 165 ( divide both sides by 2 )

x = 82.5

Answer:

--------------------------------------------------

Step-by-step explanation:

60+x-45+x=180

60-45+2x=180

15+2x=180

2x=180-15

2x=165

x=165/2

x=82.5

Find the number if 5/6 of it is 55.
kow [346]

Answer:

The unknown number is 66.

Step-by-step explanation:

We know that we need to find the number that is 55 when calculated as 5/6 or the whole number. First, we must divide 55 by 5.

55 ÷ 5 = 11

This means that 1/6 of the unknown number is 11.

Now, let's multiply 11 by 6.

11 x 6 = 66

Therefore, the unknown number is 66.

Hope this helps! :)

What percent of 600 is 12
Hitman42 [59]
<span>What percent of 600 is 12?
In order to get what percent of 600 is 12, we need to formulate the equation.

12 = ___ * 600
12 = 600P
P = 12 / 600 
P = 0.02

Percentage must be in hundred. So multiply 0.02 by 100
= 0.02 * 100
= 2%

So, 2% of 600 is equal to 12.</span>

Hope this helps!
