Answer:
<h3>The length of y is 62.82 cm.</h3>Step-by-step explanation:
We are given a right triangle with an angle 30°.
Opposite side of angle 30° is x and adjacent side is y.
Also, given length of side x=36.25 cm.
In order to find the value of y, we need to apply tangent trigonometrical ratio.
We know,
Therefore,
Plugging values of and x=36.25, we get
Plugging value of in above equation, we get
On multiplying both sides by y, we get
0.577y=36.25
Dividing both sides by 0.577, we get
y=62.82
<h3>Therefore, the length of y is 62.82 cm.</h3>Answer:
3
Step-by-step explanation:
Given
f(x) = , then
f(12) = =
= ± 3
There are 2 values 3 and - 3
The positive value of f(12) is + 3
