Answer:
Step-by-step explanation:
tan 0 = 1/ cot 0
so, tan 0=11/60,
cot 0= 1/ (11/60)
cot 0= 60/ 11

Answer:</h2>
<h2>Explanation:</h2>
The easier way to solve this problem is to graph the function using graphing calculator. Here we have the following function:
So this is a cubic function that extends to as x tends to and as x tends to . This is so because the leading coefficient (the coefficient that accompanies ) is positive. Then, this graph will pass through a point in the x-axis which is the value of the only real solution. The graph shows that this value is:
Answer:
The measure of ∠PQW is 30°
Step-by-step explanation:
Given as :
The measure of angle WQR = ∠WQR = 130°
The measure of angle PQR = ∠PQR = 16x°
The measure of angle PQW = ∠PQW = 3x°
<u>Now, From Figure</u>
Since, The measure of angle ∠PQR = The sum of measure of angle ∠PQW + The sum of measure of angle ∠WQR
∴ ∠PQR = ∠PQW + ∠WQR
Or, 16x° = 3x° + 130°
Or, 16x° - 3x° = 130°
Or, 13x° = 130°
∴ x =
I.e x = 10°
Now, we put the value of x in angles
So, The measure of angle PQW = 3x°
I.e ∠PQW = 3 × 10°
∴ ∠PQW = 30°
The measure of ∠PQW = 30°
Hence The measure of ∠PQW is 30° Answer
