Answer:
there's no picture attached
if ∡a and ∡b are complementary angles, that simply means that ∡a + ∡b = 90°.
![\bf \stackrel{\measuredangle a}{x}~~+~~\stackrel{\measuredangle b}{2x+75}~~=~~90\implies 3x=15\implies x=\cfrac{15}{3}\implies \boxed{x=5} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{\measuredangle a}{5}~\hspace{7em}\stackrel{\measuredangle b}{2(5)+75}\implies 85](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7B%5Cmeasuredangle%20a%7D%7Bx%7D~~%2B~~%5Cstackrel%7B%5Cmeasuredangle%20b%7D%7B2x%2B75%7D~~%3D~~90%5Cimplies%203x%3D15%5Cimplies%20x%3D%5Ccfrac%7B15%7D%7B3%7D%5Cimplies%20%5Cboxed%7Bx%3D5%7D%0A%5C%5C%5C%5C%5B-0.35em%5D%0A%5Crule%7B34em%7D%7B0.25pt%7D%5C%5C%5C%5C%0A%5Cstackrel%7B%5Cmeasuredangle%20a%7D%7B5%7D~%5Chspace%7B7em%7D%5Cstackrel%7B%5Cmeasuredangle%20b%7D%7B2%285%29%2B75%7D%5Cimplies%2085)

Answer:
2.6
Step-by-step explanation:
Just divide 5 by 13 to get 2.6 then times 5 and 2.6 is 13
the formula is a_{1}+(n-1) d
so a_{1} would be the first number in the sequence, which would be 13 in problem 9.
13+(n-1)d
then you put in n, which is 10 (it represents which number in the sequence you're looking for, for example 16 is the second number in the sequence)
13+(10-1)d
then you find the difference between each number, represented by d which in this case is 3
13+(10-1)3
13+(9)3
13+27=
40
