Please help quickly!!

x = 90         i hope this helps!   :)

scalene right triangle

Step-by-step explanation:

we know that all triangles are 180 degrees

we are given 53 degrees and 37 degrees

those added together is 90 degrees

180 - 90 = 90

so that leaves us with the value of x being 90 degrees. which makes it a right triangle

x + 53 + 37 = 180

combine like terms

x + 90 = 180

subtract 90 from both sides

x = 90

its scalene because the other angles (non right) are not the same. they both are not 45 degrees. an isosceles right triangle has the angle measurements of 90, 45, 45. in this case it's not.

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
