Answer:
tan theta = 2 sqrt(5) /15
Step-by-step explanation:
sin theta = opp / hypotenuse
sin theta = 2/7
We can use the Pythagorean theorem to find the length of the adjacent side
a^2 + b^2 = c^2
2^2 +adj^2 = 7^2
4 + adj^2 = 49
adj ^2 = 49-4
adj^2 = 45
Taking the square root of each side
adj = sqrt(45) = sqrt(9*5) =sqrt(9) sqrt(5) = 3 sqrt(5)
The tan theta = opp/ adj
tan theta = 2 / 3 sqrt(5)
Multiply by sqrt(5) / sqrt(5)
= 2 sqrt(5) / 3 *5
= 2 sqrt(5) /15

Answer:
1129/200 = 5.645
Step-by-step explanation:
31/8 ÷ (x-4 1/4)=17/18 +1 5/6=17/18 +11/6=17/18 +33/18=(17+33)/18=50/18=25/9
31/8 ÷ (x-4 1/4)=25/9
x-4 1/4 = 31/8 ÷25/9 = 31/8 × 9/25 = 279/200
x = 4 1/4 + 279/200 = 17/4 + 279/200 = 850/200 + 279/200 = 1129/200 = 5.645
