The measures of the angels are 24 and 30 and (3x-9) what is x

x=45

Step-by-step explanation:

Okay then. In a triangle, the all three angle values combined equals to 180 degrees. So 24+30+(3x-9)=180. Then, you can solve for x.

24+30+(3x-9)=180         Equation

45+3x=180                     Combine like terms

3x=135                            Subtract 45 from both sides

x=45                                Divide both sides by 3

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
