(Right angle Trigonometry) help me solve for X please!
Vinvika [58]

Answer:

x = 52.0

Step-by-step explanation:

Reference angle = 68°

Length of side Opposite to reference angle = x

Adjacent length = 21

Apply the trigonometric function, TOA, which is given as:

Tan 68° = Opp/Adj

Substitute

Tan 68° = x/21

21 × Tan 68° = x

51.9768238 = x

x = 51.9768238 ≈ 52.0 (approximated to nearest tenth)

Is the value of the 1 in 1,440,000 10 times as great as the value of the 4 in the hundred thousands place ? Explain
Burka [1]
I do not think so, because it has to be the same number.
Ex: 5,539 - in this the 5 in the thousands place is greater than the 5 in the hundreds place
