Help me solve this and pls explain

Measure of Arc JM = 160°

Step-by-step explanation:

We know that the sum of the measures of the angles within a circle all add up to 360°, so we can say:

(53) + (79) + (68) + (Arc JM) = 360

200 + Arc JM = 360

Arc JM = 360 - 200

Arc JM = 160

Hope this helps!

mJM = 360 - (53 + 79 + 68)

mJM = 360 - 200

mJM = 160º

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
