3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6

X= 5 3/8

Step-by-step explanation:

3 1/8 ÷(5 3/8 - 4 7/28) = 25

9  = 27

9

≅ 2.7777778

17/18 + 1 5/6 = 25

9  = 27

9  ≅ 2.7777778

2.7777778=2.7777778

X=5 3/8

hope this helps have a great day

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
